Which of these conjugated dying's will not react are dienes that are in cisoid forn, which can react in dieals alder. In general, electron-withdrawing groups on the dienophile speed up Diels-Alder processes.
The locked trans dienes do not react in the Diels-Alder reaction, whereas the cyclic cis dienes are so reactive that they may react with one another, making these conformations two extremes. Because one molecule serves as the diene and the other as the dienophile, for instance, cyclopentadiene dimerizes. Bridged bicyclic compounds are produced by cyclic dienes. Diels-Alder reactions can only occur in conjugated dienes with the s-cis structure. A diene cannot conduct a Diels-Alder reaction if it is not conjugated or cannot be in the s-cis configuration. Ring-based dienes are incapable of rotating, hence

5. A solid consists of a mixture of NaNO3 and Mg(NO3)2. When 6.50 g of the solid is dissolved in 50.0 g of water, the freezing point of the solution is lowered by 5.23°C. What is the composition by mass of the solid mixture?
The mass of the solid mixture can be determined from the molality and depression in freezing point of the solution. The mass obtained for the solution is 46.4 g.
What is depression in freezing point?Freezing point of a solution decreases from that of pure solvent when a non-volatile solute is added into it. The depression in freezing point ΔT is proportional to the molality of the solution.
ΔT = Kf m
Where Kf is the molal depression constant. Kf for water is 1.86 K /(mol Kg)
Given that ΔT = 5.23 °C
m = ΔT / Kf
= 5.23 °C / 1.86 K /(mol Kg)
= 2.811 m
Molality = no.of moles of the solid mixture/ mass of solvent in Kg.
no. of moles = molality × solvent mass
= 2.811 m × 0.05 Kg = 0.140 moles
Given the weight of the solid mixture = 6.50g
Hence, its composition by mass = 6.50/ 0.140 moles = 46.4 g.

write short note about acid nomenclature
Acids
There are various definitions for an acid. The simplest description of an acid is a chemical molecule with one or more hydrogen atoms that, when dissolved in water, gives forth hydronium ions (H3O+).
Because acids are molecular, they do not assume the expanded three-dimensional structures of ionic substances like NaCl and remain single molecules in their pure form. However, when these molecules are dissolved in water, a positively charged anion and a hydronium ion are produced as a result of the chemical connection between the hydrogen atom and the remainder of the molecule breaking. An equation involving chemicals can represent this:
HCl+H2O→H3O++Cl−
In an inorganic acid's formula, the H of the acid is written first. After the acid dissolves, the anion is all that is left of the acid (apart from the H). Although a significant class of chemicals, organic acids are not covered in this article.
Acid Names
Since all acids contain hydrogen, an acid's name is determined by the anion that it is associated with. These anions come in monatomic and polyatomic forms.
Binary acid names (in aqueous form)
An acid that contains hydrogen and another element is referred to as a binary acid. The majority of binary acids have a halogen in them. The prefix hydro- is used to start an acid name, which is then followed by the base name of the anion and the suffix -ic.
Oxyacids name
An oxyacid is an acid made up of three elements: hydrogen, oxygen, and another one. Typically, the third element is a nonmetal.
a) Oxyanions with the -ite end.
The anion's root is followed by the suffix -ous to form the name of the acid. No prefix is present.
b)Oxyanions that end in -ate.
The anion's root and the suffix -ic are used to identify the acid. No prefix is present.
In conclusion
Acids are molecular substances that discharge hydrogen ions.
The two elements hydrogen and the other make up a binary acid.
Hydrogen, oxygen, and another element are all present in oxyacids.
The anion that is bound to the hydrogen provides the basis for the acid's name.

Powerful molecular forces Intermolecular forces that are weak Answer bank High surface tension, high viscosity, high vapor pressure, and high boiling point.
A liquid's resistance to flowing is determined by its viscosity. Viscosity is a measure of how strongly intermolecular forces are present in a liquid. All four parameters—boiling point, melting temperature, surface tension, and viscosity—decline significantly. The substance's vapor pressure rises as a result of the molecules' easy escape due to weak forces. In a closed container, vapor pressure develops when liquid molecules have enough kinetic energy to break free from the intermolecular interactions and transform into a gas. The magnitude of intermolecular forces has an inverse relationship with vapor pressure.

A covalent bond occurs when atoms share one or more pairs of electrons to form a stable molecule. The difference in electronegativity between two atoms plays a role in determining the type of bond formed between them. In general, covalent bonds are formed between atoms with similar electronegativities.
A covalent bond can form between two atoms if the electronegativity difference between them is less than 1.7. However, the size of the atoms is not the determining factor in covalent bond formation. Instead, the atomic electron distribution and electron affinity are very important.
In general, covalent bonding is a key process in chemistry that allows atoms to form stable bonds with each other. It is a key factor in determining the properties of various chemical compounds such as gases, liquids and solids.

17.0g of potassium acetate is dissolved in 250.mL of a 0.30M aqueous solution of sodium chromate. The final molarity of acetate anion in the solution is 0.59 M.
The term "molar concentration" refers to the amount of a substance in a solution represented as a percentage of its volume. It is also used to refer to molarity, quantity concentration, or substance concentration. The most common unit used in chemistry to express molarity is the number of moles per liter, represented by the unit sign mol/L or mol/dm3 in SI units. One molar, or 1 M, of a solution's concentration is defined as one mol/L. Molarity is a unit of concentration used to describe chemical solutions (M). It is the number of moles of the solute in one liter of solution. This is not the same as the liters of solvent, to be clear (a common mistake). Despite being a useful unit, molarity has one fundamental flaw. Because temperature affects a solution's volume, it does not remain constant when it varies. Because you cannot directly measure solute in moles, you usually convert grams of solute to moles and then divide this amount by liters of solution.

The salt will help to draw out moisture from the potatoes, making them firmer and more suitable for baking. Submerge the potatoes in the water and let them soak for at least 30 minutes.
Drain the water and pat the potatoes dry with a paper towel. This will remove any excess moisture and help them to crisp up when baking. You can then season the potatoes as desired and bake them as normal. The soaking process helps to rehydrate the potatoes, making them firmer and more suitable for baking.
The salt also helps to draw out moisture, so that when the potatoes are baked, they will be crisp on the outside and fluffy on the inside. The soaking process is an important step in preparing potatoes for baking, as it helps to make them firmer and more suitable for baking.
