Question

(+)2- Methylbutan- 1-ol and (-) 2- Methylbutan-1-ol have different values for which property ?

• A. Boiling point
• B. Relative density
• C. Refractive index
• D. Specific rotation

Answer 1

The correct option is A Boiling point

(+)2- Methylbutan- 1-ol and (-) 2- Methylbutan-1-ol have different values for boiling point.

Enantiomers differ in physical properties such as melting/ boiling point.
However, they have the same relative density, refractive index and specific rotation.

The magnitude of specific rotation is the same but their sign is opposite.

Hence the correct option is A.
