How many molecular of H2O and O2 are present in 8.5g of H2O2 ?
2H2O+O2--->2H2O2
8.5 gm H2O2=0.25 mole
hence H2O is also 0.25 mole i.e.4.5 gm
O2is 0.125 mole i.e.4 gm
Select the structure that corresponds
to the name:
decanoic acid
COOH
A.
B. CH3(CH2)7COOH
C. both
Answer:
b
Explanation:
Molecular formula of Decanoic Acid is C₁₀H₂₀O₂ therefore Option A is the right answer.
What is Decanoic Acid ?Decanoic Acid is a C10 , straight chain , saturated fatty acid . Its general formula is C₁₀H₂₀O₂ .
In the first option we can see a straight chain , saturated fatty acid and the molecular formula is also same as decanoic acid .
In second option the molecular formula is C₉H₁₈O₂ which is not same as Decanoic Acid.
Hence option A is the right answer.
