Paragraph: Two aliphatic aldehydes P\mathrm{P} and Q\mathrm{Q} react in the presence of aqueous K2CO3\mathrm{K}_2 \mathrm{CO}_3 to give compound R, which upon treatment with HCN provides compound S\mathrm{S}. On acidification and heating, S gives the product shown below :Paragraph: Two aliphatic aldehydes P and Q react in the presence of aqueous K_2 CO_3 to give compound R, which upon
Question: The compounds PP and QQ respectively are

Options

  1. AWhat is the order of basicity among the following compounds?
  2. BWhat is the order of basicity among the following compounds?
  3. CWhat is the order of basicity among the following compounds?
  4. DWhat is the order of basicity among the following compounds?

Correct answer

B. What is the order of basicity among the following compounds?

Step-by-step solution

Paragraph: Two aliphatic aldehydes P and Q react in the presence of aqueous K_2 CO_3 to give compound R, which upon
Some inferences from above data - aq K2CO3a q \mathrm{~K}_2 \mathrm{CO}_3 can facilitate aldol condensation to aliphatic aldehydes. - HCN can lead to cyanohydrin formation - H+,Δ\mathrm{H}^{+}, \Delta can lead to hydrolysis of cyanide to acid and following esterification. So SS is cyanohydrin.Paragraph: Two aliphatic aldehydes P and Q react in the presence of aqueous K_2 CO_3 to give compound R, which upon
