Answer to Problem 14.29P
Propanol is a primary alcohol.
Explanation of Solution
Alcohols are the organic compounds with the general formula R-OH. Here, the −OH group (hydroxyl group) is directly bonded to the carbon atom of the parent chain. On the basis of the carbon atom to which the −OH group is bonded, alcohols can be classified as primary, secondary and tertiary alcohols.
- Primary alcohol = The −OH group must be bonded to the primary carbon atom (bonded with one other C atom).
- Secondary alcohol = The −OH group must be bonded to the secondary carbon atom (bonded with two other C atoms).
- Tertiary alcohol = The −OH group must be bonded to a tertiary carbon atom (bonded with three other C atoms).
In the given alcohol, the −OH group is bonded to a primary C atom which is bonded with one other C atom hence, it should be primary alcohol.

Concept Introduction:
Organic compounds are the compounds that are mainly composed of C and H atoms. The branch of chemistry that deals with the preparation, reactions, and properties of organic compounds are said to be organic chemistry. The molecular formula of the organic compound represents the number of bonded atoms with their atomic symbols. The structural formula represents all the bonded atoms with chemical bonds and the arrangement of atoms in the molecule.
Answer to Problem 14.29P
3-ethyl-3-pentanol is a tertiary alcohol.
Explanation of Solution
Alcohols are the organic compounds with the general formula R-OH. Here the −OH group (hydroxyl group) is directly bonded to the carbon atom of the parent chain. On the basis of the carbon atom to which the −OH group is bonded, alcohols can be classified as primary, secondary and tertiary alcohols.
- Primary alcohol = The −OH group must be bonded to the primary carbon atom (bonded with one other C atom).
- Secondary alcohol = The −OH group must be bonded to the secondary carbon atom (bonded with two other C atoms).
- Tertiary alcohol = The −OH group must be bonded to a tertiary carbon atom (bonded with three other C atoms).
In the given alcohol, the −OH group is bonded to a tertiary C atom which is bonded with 3 other C atoms hence, it should be tertiary alcohol.

Answer to Problem 14.29P
2,2-dimethylcyclohexanol is a secondary alcohol.
Explanation of Solution
Alcohols are the organic compounds with the general formula R-OH. Here the −OH group (hydroxyl group) is directly bonded to the carbon atom of the parent chain. On the basis of the carbon atom to which the −OH group is bonded, alcohols can be classified as primary, secondary and tertiary alcohols.
- Primary alcohol = The −OH group must be bonded to the primary carbon atom (bonded with one other C atom).
- Secondary alcohol = The −OH group must be bonded to the secondary carbon atom (bonded with two other C atoms).
- Tertiary alcohol = The −OH group must be bonded to a tertiary carbon atom (bonded with three other C atoms).
In the given alcohol, the −OH group is bonded to a secondary C atom which is bonded with two other C atoms hence, it should be secondary alcohol.
