Hint: Primary alcohols are those compounds in which the carbon that contains the alcohol group is attached to further one carbon atom. Secondary alcohols are those compounds in which the carbon that contains the alcohol group is attached to further two carbon atoms. Tertiary alcohols are those compounds in which the carbon that contains the alcohol group is attached to further three carbon atoms.
Complete step by step answer:
So the compound has formula , this has five carbon atoms. This compound has 8 isomers in which we can classify them as primary, secondary, and tertiary alcohols.
Pentan-1-ol, this is a straight-chain compound, and the carbon that contains the alcohol group is attached to further one carbon atom so it is primary. The structure is given below:
2-Methyl butanol, this is a branched form of and the carbon that contains the alcohol group is attached to further one carbon atom so it is primary. The structure is given below:
3-Methyl butanol, this is a branched form of and the carbon that contains the alcohol group is attached to further one carbon atom so it is primary. The structure is given below:
2,2-Dimethyl propanol, this is a branched form of and the carbon that contains the alcohol group is attached to further one carbon atom so it is primary. The structure is given below:
Pentan-2-ol, this is a straight-chain with alcohol at the second position, and the carbon that contains the alcohol group is attached to further two carbon atoms so it is secondary. The structure is given below:
3-Methyl-2-butanol, this is a branched form, and the carbon that contains the alcohol group is attached to further two carbon atoms so it is secondary. The structure is given below:
Pentan-3-ol, this is a straight-chain with alcohol at the third position, and the carbon that contains the alcohol group is attached to further two carbon atoms so it is secondary. The structure is given below:
2-Methyl-2-butanol, this is a branched form, and the carbon that contains the alcohol group is attached to further three carbon atoms so it is tertiary. The structure is given below:
Note: You may think that the alcohol attached to the number of carbon atoms will classify them as primary, secondary, and tertiary, but it is the number of carbon atoms further attached to the carbon atom having an alcohol group.
Complete step by step answer:
So the compound has formula
Pentan-1-ol, this is a straight-chain compound, and the carbon that contains the alcohol group is attached to further one carbon atom so it is primary. The structure is given below:

2-Methyl butanol, this is a branched form of

3-Methyl butanol, this is a branched form of

2,2-Dimethyl propanol, this is a branched form of

Pentan-2-ol, this is a straight-chain with alcohol at the second position, and the carbon that contains the alcohol group is attached to further two carbon atoms so it is secondary. The structure is given below:

3-Methyl-2-butanol, this is a branched form, and the carbon that contains the alcohol group is attached to further two carbon atoms so it is secondary. The structure is given below:

Pentan-3-ol, this is a straight-chain with alcohol at the third position, and the carbon that contains the alcohol group is attached to further two carbon atoms so it is secondary. The structure is given below:
