Which of the following alcohol is optically active?

∴ 2-butanol having chiral carbon atom, is optically active.

Which is optically active?

A compound capable of optical rotation is said to be optically active. All pure chiral compounds are optically active. eg: (R)-Lactic acid (1) is chiral and rotates the plane of plane-polarized light.

Why Mesotartaric acid is optically inactive?

Meso tartaric acid has a plane of symmetry and is achiral. Meso tartaric acid is optically inactive because of internal compensation that means one half of the molecule is neutralized by another. Hence, the correct option is A, molecular symmetry.

How do you calculate total number of optical isomers?

– The number of optical isomers of a compound is determined by calculating the number of chiral centres in it. – The maximum number of optical isomers is given by the formula ${{2}^{n- 1}}$, where n is the number of chiral centres. So, the correct answer is option B.

How many stereoisomers are optically active?
