classify each of the molecules below.\nprimary alcohol\nsecondary alcohol\ntertiary alcohol\nquaternary…

Explanation:

Step1: Recall alcohol - classification rules

Alcohols are classified based on the carbon - atom to which the hydroxyl group ($-OH$) is attached. A primary alcohol has the $-OH$ group attached to a carbon that is bonded to only one other carbon atom. A secondary alcohol has the $-OH$ group attached to a carbon that is bonded to two other carbon atoms. A tertiary alcohol has the $-OH$ group attached to a carbon that is bonded to three other carbon atoms. There is no such thing as a quaternary alcohol.

Step2: Analyze the first molecule

The first molecule has the $-OH$ group attached to a carbon that is bonded to only one other carbon atom. So it is a primary alcohol.

Step3: Analyze the second molecule

The second molecule has the $-OH$ group attached to a carbon that is bonded to two other carbon atoms. So it is a secondary alcohol.

Step4: Analyze the third molecule

The third molecule has the $-OH$ group attached to a carbon that is bonded to only one other carbon atom. So it is a primary alcohol.

Answer:

First molecule: primary alcohol Second molecule: secondary alcohol Third molecule: primary alcohol
