Answer:
An alcohol with three other carbons attached to the carbon with the hydroxyl group
An alcohol with two other carbons attached to the carbon with the hydroxyl group
Step-by-step explanation:
If we look at 3-ethyl-3-pentanol, we will discover that the compound is a tertiary alcohol. That is, the carbon atom bearing the hydroxyl group is attached to three other carbon atoms as gown in image 1 attached.
For 2-hexanol, the carbon atom bearing the hydroxyl group is attached to two other carbon atoms hence the alcohol is a secondary alcohol. The compound is shown in image 2 attached.
