Propanoic acid reacts with LiAlH4 to give organic product P. Methanoic acid reacts with organic product P, in the presence of a few drops of concentrated sulfuric acid, to give organic product Q. What are the skeletal formulae of the two organic products?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
A[organic product P: skeletal formula of CH3CH2CH2OH, organic product Q: skeletal formula of HCOOCH2CH2CH3]
B[organic product P: skeletal formula of CH3CH2CH2OH, organic product Q: skeletal formula of HCOOCH(CH3)2]
C[organic product P: skeletal formula of CH3CH(OH)CH3, organic product Q: skeletal formula of HCOOCH2CH2CH3]
D[organic product P: skeletal formula of CH3CH(OH)CH3, organic product Q: skeletal formula of HCOOCH(CH3)2]
✓ Correct answer
B: [organic product P: skeletal formula of CH3CH2CH2OH, organic product Q: skeletal formula of HCOOCH(CH3)2]
