Chapter 4.1, Problem 2QQ

Interpretation Introduction

Interpretation:

The arrangement of bonds about the carbon atom of carbonyl group is in which geometry has to be identified from the given options.

Concept Introduction:

Carbonyl groups are the one which contain a double bond between carbon and oxygen atom.  Aldehydes and ketones possess this carbonyl functional group in it.  The structural representation of a carbonyl group can be given as shown below,

The arrangement of atoms around the carbon atom in a carbonyl group is a trigonal planar arrangement.  The bond angle that have less strain between the other bonds is $\text{120}\text{°}$.
