Detailed explanation-1: -Chiral compound is optical active. Achiral compound is optical inactive. The sample containing a chiral compound rotates the plane of polarization of plane-polarized light, and the direction and angles of the rotation depend on the nature and concentration of the chiral substances.

Detailed explanation-2: -Optically active compounds rotate the plane of polarised light.

Detailed explanation-3: -Which of the following compounds does not rotate the plane polarised light? Solution : 4-Hydroxyheptane, due to absence of asymmetric carbon atom does not rotate the plane polarised light.
