Embibe Experts Solutions for Chapter: Aldehydes, Ketones and Carboxylic Acids, Exercise 1: NEET - 13th September 2020

$\mathrm{RMgX}+{\mathrm{CO}}_2\underset{\mathrm{ether}}{\overset{\mathrm{dry}}{\to }}\mathrm{Y}\stackrel{{\mathrm{H}}_3{\mathrm{O}}^{+}}{⟶}\mathrm{RCOOH}$

What is $\mathrm{Y}$ in the above reaction?

Match List - I with List - II.

Choose the correct answer from the options given below:

Given below are two statements:
Statement $\mathrm{I}$: The boiling points of aldehydes and ketones are higher than hydrocarbons of comparable molecular masses because of weak molecular association in aldehydes and ketones due to dipole - dipole interactions.
Statement $\mathrm{II}$: The boiling points of aldehydes and ketones are lower than the alcohols of similar molecular masses due to the absence of $\mathrm{H}$-bonding.

In the light of the above statements, choose the most appropriate answer from the options given below :

Which one of the following is not formed when acetone reacts with $2$-pentanone in the presence of dilute $\mathrm{NaOH}$ followed by heating?

Compound $\mathrm{X}$ on reaction with ${\mathrm{O}}_3$ followed by $\mathrm{Zn}/{\mathrm{H}}_2\mathrm{O}$ gives formaldehyde and $2$-methyl propanal as products. The compound $\mathrm{X}$ is:
