Step-by-Step Solution

Answer

Common name corresponding to given structures are:

(a)  Acetaldehyde: 

(b)  Butyl methyl acetone:

(c)  Formaldehyde:

Part (a) Step 1: Given Information

We  need to identify the given compound as their common names:

Part (a) Step 2: Explanation

We are given a compound in which $-CHO$ group is present as functional group. So, Compound given is aldehyde. It's IUPAC name is ethanal as it contains only two carbon atom. Common name of ethanal is acetaldehyde.

Part (b) Step 1: Given Information

We  need to identify the given compounds as their common names:

Part (b) Step 2: Explanation

We are given a compound in which $C=O$is present as functional group. So compound given is ketone. Also it contains five carbon atoms so it's IUPAC name is $2-$pentanone. Common name of $2-$pentanone is butyl methyl acetone.

Part (c) Step 1: Given Information

We  need to identify the given compounds as their common names:

Part (c) Step 2: Explanation

We are given a compound in which $-\mathrm{CHO}$ group is present as functional group. Compound given is simplest aldehyde. It's IUPAC name is methanal as it contains only one carbon atom. Common name of methanal is formaldehyde.
