Question

Cyclohexanol is a?

• A. Primary alcohol
• B. Secondary alcohol
• C. Tertiary alcohol
• D. Phenol

Answer 1

The correct option is B

Secondary alcohol

Explanation for the correct option:

Option(B):Secondary alcohol

• The Alcohols are classified as primary, secondary, and tertiary depending upon if the Hydroxyl group is attached to the primary, secondary, or tertiary Carbon atom.
• Whereas the Carbon atoms are classified based on the attachment of the Carbon with the adjacent group as primary${\text{1}}^{\text{o}}$, secondary${\text{2}}^{\text{o}}$, and tertiary${\text{3}}^{\text{o}}$.
• In Cyclohexanol, the Hydroxyl $-\text{OH}$group is attached to one of the Carbon atoms of the Cyclohexane which is a secondary Carbon.
• Thus, as the Carbon atom bearing a Hydroxyl group is secondary carbon, it represents as Cyclohexanol as secondary alcohol, for which the figure can be shown as:

Explanation for the incorrect option:

Option(A): Primary alcohol

• Cyclohexanol is not Primary alcohol.
• Hence, the given option does not correspond to the correct concept.

Option(C):Tertiary alcohol

• Cyclohexanol is not considered Tertiary alcohol.
• Hence, the given option does not represent the correct concept.

Option(D):Phenol

• Cyclohexanol is not represented as a Phenol.
• Thus the given option is an incorrect one.

Hence, Cyclohexanol is a Secondary alcohol.
