your answer is wrong. please read the explanation for more help.
classify each of the molecules below.
primary alcohol
secondary alcohol
tertiary alcohol
quaternary alcohol
primary alcohol
secondary alcohol
tertiary alcohol
quaternary alcohol
primary alcohol
secondary alcohol
tertiary alcohol
quaternary alcohol

Explanation:

Step1: Recall alcohol - classification rules

Primary alcohol has the -OH group attached to a carbon that is bonded to only one other carbon. Secondary alcohol has the -OH group attached to a carbon that is bonded to two other carbons. Tertiary alcohol has the -OH group attached to a carbon that is bonded to three other carbons. There is no quaternary alcohol as the concept doesn't exist in alcohol - classification.

Step2: Analyze the first molecule

The -OH group is attached to a carbon that is bonded to two other carbons, so it is a secondary alcohol.

Step3: Analyze the second molecule

The -OH group is attached to a carbon that is bonded to two other carbons, so it is a secondary alcohol.

Step4: Analyze the third molecule

The -OH group is attached to a carbon that is bonded to only one other carbon, so it is a primary alcohol.

Answer:

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