Detailed explanation-1: -The complex [Co(NH3)3Cl3] does not have optical isomers due to presence of an element of symmetry.

Detailed explanation-2: -Optical isomerism is a type of stereoisomerism in which the isomers have the same molecular formula and the structural formula but differ in their direction of rotation of plane polarized light.

Detailed explanation-3: -The difference between structural and optical isomers in carbohydrates is that structural isomers are different structures of the same chemical formula, whereas optical isomers are different mirror images of the same structure.

Detailed explanation-4: -Which of the following does not show optical isomerism? en = ethylenediamine.

Detailed explanation-5: -For example, one of the optical isomers (enantiomers) of the amino acid alanine is known as (+)alanine. A solution of the other enantiomer rotates the plane of polarisation in an anti-clockwise direction. This enantiomer is known as the (-) form. So the other enantiomer of alanine is known as or (-)alanine.
