Question

Which of the following statement/s is incorrect?
(A) The presence of chiral carbon is not the essential condition for
enantiomerism.
(B) Diasteromers have different physical properties and similar but
not identical chemical properties.
(C) Enantiomers have the same physical & chemical properties but
different physiological properties.
(D) Only organic molecules show optical isomerism.​

Answer 1

Answer:

A False

B True

C True

D False

Explanation:

(A)The necessary and sufficient condition is that the molecule must not be superimposable on its mirror image.

(B) Diastereomers have different physical properties (such as melting and boiling points) and similar but not identical chemical properties (such as rates of reaction, selectivity and specificity etc).

(C) Enantiomers have the same physical and chemical properties (such as melting and boiling points) but different physiological properties (such as one enantiomer acts as a drug and the other enantiomer is toxic).

(D) Both organic and inorganic molecules (coordination compounds) show optical isomerism
