`(+2) ` 2-methylbutan -1-ol(-)2-methylbutan -1-of have different values for which

A

Boiling point

B

Relative density

C

Refractive index

D

Specific rotation

Text Solution

Verified by Experts

The correct Answer is:
D
(+) 2-methyl butan-1-ol and (-) 2-methyl butan-1-ol are enantiomer. They are non-superimposable mirror images of each other. Hence, they are optically active.
The optial activity of a compound can be confirmed by the value of specific rotation. It is defined as the rotation produced by solution of 10 cm length and uniti concentration (1g/mL) for the given `lambda` of light at the given temperature.
