Chapter 12.10, Problem 1QQ

Interpretation Introduction

Interpretation:

The total number of carbon atoms that a secondary carbon atom is directly bonded to has to be found from the given options.

Concept Introduction:

In a hydrocarbon structure, each and every carbon atoms are classified as primary, secondary, tertiary, and quaternary carbon atom.

If a carbon atom in an organic molecule is directly bonded to only one another carbon atom is known as primary carbon atom.

If a carbon atom in an organic molecule is directly bonded to two other carbon atoms is known as secondary carbon atom.

If a carbon atom in an organic molecule is directly bonded to three other carbon atoms is known as tertiary carbon atom.

If a carbon atom in an organic molecule is directly bonded to four another carbon atom is known as quaternary carbon atom.

These carbon atoms are denoted by notations as, $1°$ for primary, $2°$ for secondary, $3°$ for tertiary and $4°$ for quaternary.
