Q. 12.58 - An Introduction to General, Organic, and Biological Chemistry

Question

Draw  the condensed structure or line formula of each of following:

(a) Formaldehyde
(b) $2-$chloro butanal

(c) $3-$methyl $2-$hexanone

(d) $3,5$dimethyl hexanal

Step-by-Step Solution

Answer

Line angle formula corresponding to given compounds are:

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

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 $2 chlorobu\tan al$ 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 $3,5$ dimethyl hexanal is
