Question

Which of the noncyclic isomers of bromochloropropene is (are) optically active?

Short answer

3-Bromo-3-chloroprop-1-ene is optically active.

Step-by-step solution

Optically active substances

If the polarized light moves through a solution having a chiral compound, it causes the rotation of the plane of vibration. This rotation of the plane of polarized light is known as optical activity. The molecules or substances that results in the rotation of the plane of polarized light are called optically active.

To find non cyclic isomers of bromochloropropene

The non-cyclic isomer of bromochloropropene that is optically active has a chiral center, in this molecule, the chiral center is the carbon atom, which is bound to four different groups.

Hence, 3-Bromo-3-chloroprop-1-ene is optically active.
