Question

Enantiomers have:
This question has multiple correct options
1.All physical properties are the same except their action on plane polarized light which is equal in magnitude but opposite in direction.
2.All chemical properties are the same except when reagent is chiral in that case the reactivity of enantiomers will be different.
4.Opposite configuration of all chiral centers according to the CIP rule.
4.Superimposable image of each other.

Answer 1

We have to know enantiomers are one type of stereoisomers, which are mirror images of each other that are not identical. Each member of the pair is known as enantiomorph and the structural things are called enantiomerism. When the molecules are within the detection limits, and have one chiral centre, then it is called as enantiopure compounds.

Complete step by step answer:
We know that the compounds that form non-superimposable mirror images of each are called optical isomers and a chiral molecule has no plane of symmetry in the molecule. This property is known as chirality.
If four different groups are bonded to a tetrahedral atom, the four groups could be arranged in two possible ways. The two compounds which result are mirror images of each other. These two isomers are called enantiomers.
The pairs of compounds with exactly the same connectivity but opposite three-dimensional shapes are enantiomers.
We have to know enantiomers are not the same as each other; one enantiomer cannot be superimposed on the other.
Enantiomers have no mirror planes and do not have two equal and opposite halves.
They have similar properties, but the optical rotation is different.
Two enantiomers contain an equal but opposite rotation in plane polarized light
The rotation of light is in clockwise direction in (+) enantiomers and rotation of light is anticlockwise direction in (-) enantiomers.
We have to know that enantiomers have similar physical properties, but differ in the optical rotation. When plane polarized light is placed they rotate in the opposite direction, but the magnitude is the same.
Therefore, the option (A) is correct.
We have to know that enantiomers have different configurations at the stereogenic centre because they are mirror images to each other.
Therefore, the option (C) is correct.
Enantiomers are not superimposable.
Therefore, the option (D) is incorrect.

So, the correct answer is Option A,C.

Note: We have to know that racemic mixture (or) racemate is the mixture of equal numbers of both enantiomers. The amount of positive rotation is the same as the amount of negative rotation in a racemic mixture, therefore the net rotation is zero. Enantiomer members have various chemical reactions with other enantiomer substances.
