Answer #1

Concepts and reason

This is based on the concept of stereochemistry. One of the most important topics of stereochemistry is chirality of the molecule. A molecule is said to be chiral if its mirror image is non-superimposable. A carbon is said to be a chiral carbon if all the substituents attached to it are different.

Fundamentals

Stereochemistry is sub-part of chemistry which involves the study of spatial arrangement of atoms. These spatial organization forms the structure of molecules.

Chirality is a geometric property of some of the molecules with the presence of asymmetric center and this asymmetric center leads to chirality of in the molecule.

Structure 1:

Н
(S)-3-methylhexane

All the atoms linked to carbon atoms are different.

Therefore, structure 1 is optically active.

Structure 2:

(R)-3-methylhexane

All the atoms linked to carbon atoms are different.

Therefore, Structure 2 is optically active.

Ans:

Structure 1 is optically active.

Structure 2 is optically active.
