Question

Magnitude of specific rotation of a compound is independent of:

• A. solvent
• B. concentration
• C. length of tube
• D. temperature

Answer 1

The correct option is A solvent

Specific rotation of a compound is given as change in orientation of mono-chromatic polarized light per unit-distance concentration product.

${\left[\alpha \right]}_{\partial }^{\theta }=\alpha /yl$

do not depend on solvent.

$\alpha \Rightarrow$ angle

$y\Rightarrow$ concentration

$l\Rightarrow$ length

$\theta \Rightarrow$ temperature

$\partial \Rightarrow$ wavelength
