Question

Which of the following isomerism can be exhibited by the given compound?

• A. Tautomerism
• B. Optical isomerism
• C. Geometrical isomerism
• D. Geometrical and optical isomerism

Answer 1

The correct option is B Optical isomerism

The given compound exhibits optical isomerism as it contains chiral carbon atom (carbon atom attached to 4 different atoms/groups of atoms). It exists in the form of d and l isomers.
Geometrical isomerism is not possible as two methyl groups are attached to doubly bonded carbon atoms.
