Short Answer

Expert verified

IUPAC name of given compounds are:

(a) Methane: ${CH}_{4}$

(b) Propane:

(d) Nonane:

Step by step solution

Part(a) Step 1: Given Information

We need to give IUPAC name of following compound: ${CH}_{4}$

Part (a) Step 2: Explanation

As the given compound contains $1$ carbon atoms in straight chain and all are single bonds. So compound is alkane with one carbon atom. Hence, IUPAC name of compound is methane.

Part(b) Step 1: Given Information

We need to give IUPAC name of following compound :

Part (b) Step 2: Explanation

As the given compound contains $3$ carbon atoms in straight chain and all are single bonds. So compound is alkane with three carbon atom. Hence, IUPAC name of compound is propane.

Part(c) Step 1: Given Information

We need to give IUPAC name of following compound :

Part (c) Step 2: Explanation

As the given compound contains $5$ carbon atoms in closed ring structure and all are single bonds. So compound is cycloalkane with five carbon atom. Hence, IUPAC name of compound is cyclopentane.

Part(d) Step 1: Given Information

We need to give IUPAC name of following compound:

Part (d) Step 2: Explanation

As the given compound contains $9$ carbon atoms in straight chain and all are single bonds. So compound is alkane with nine carbon atom. Hence, IUPAC name of compound is nonane.
