Question

An organic compound $A$ has the molecular formula $C_3{H}_{6}O$ it undergoes iodoform test. When saturated with dil. $HCl$ is gives $B$ of molecular formula $C_9{H}_{14}O$. $A$ and $B$ respectively are:

• A. Propanol and mesitylene
• B. Propanone and mesityl oxide
• C. Propanone and 2,6-dimethyl-2,5 heptadien-4-one
• D. Propanone and mesitylene oxide

Answer 1

The correct option is C Propanone and 2,6-dimethyl-2,5 heptadien-4-one

A can give Iodoform test.

A must be ketone with atleast one methyl group attached to carbonyl

Thus A with molecular formula Eg $C_3{H}_{6}O$ is refer to fig 1.

On Propanone if we add

refer to fig2.
