(c) $3-$methyl role="math" localid="1653538534568" $2-$hexanone

(d) $3,5$dimethyl hexanal

Short answer

Line angle formula corresponding to given compounds are:

1. Formaldehyde:
2. $2$chlorobutanol:
3. $3$methyl $2$hexanone:
4. $3,5$dimethyl hexanal:

Step-by-step solution

Part (a) Step 1: Given Information

We need to draw the structure of given compound.

Part (a) Step 2: Explanation

Formaldehyde is common name of acetaldehyde that is simplest aldehyde consisting of $-\mathrm{CHO}$group as functional group.

So, the structure of formaldehyde is

Part (b) Step 1: Given Information

We need to draw the structure of$2$chlorobutanol

Part (b) Step 2: Explanation

Compound $2-$chlorobutanal is an aldehydic compound of four carbon atoms with chlorine group as substituent at $2^{nd}$position

The structure of $2chlorobu\tan al$is

Part (c) Step 1: Given Information

We need to draw the structure of $3-$methyl $2-$hexanone

Part (c) Step 2: Explanation

Compound $3-$methyl $2-$hexanone is straight chain ketone of six carbon atoms, ketonic group present on $2^{nd}$carbon atom and having methyl as substituent at $3^{rd}$position.

The structure of $3-$methyl $2-$hexanone is :

Part (d) Step 1: Given Information

We need to draw the structure of$3,5$dimethyl hexanal

Part (d) Step 2: Explanation

Compound $3,5$dimethyl hexanal is aldehydic compound of six carbon atom in straight chain and two dimethyl groups as substituent at position $3$and $5$on straight chain.

So, the structure of localid="1653539930991" $3,5$dimethyl hexanal is
