Question

question 3 (1 point)
which of the following alcohols is classified as a secondary alcohol?
isobutyl alcohol
ethyl alcohol
isopropyl alcohol
methyl alcohol
butyl alcohol

Explanation:

• Isobutyl alcohol: It is a primary alcohol as the -OH group is attached to a carbon that is bonded to one other carbon.
• Ethyl alcohol: It is a primary alcohol since the -OH group is attached to a carbon bonded to one other carbon.
• Isopropyl alcohol: It is a secondary alcohol. The -OH group is attached to a carbon that is bonded to two other carbons.
• Methyl alcohol: It is not a secondary alcohol. The -OH group is attached to a carbon (the only carbon in methanol) which is not bonded to two other carbons.
• Butyl alcohol (assuming n - butyl alcohol): It is a primary alcohol as the -OH group is attached to a terminal carbon (bonded to one other carbon).

Answer:

Isopropyl alcohol
