Statement I: Molecules that are non-superimposable on their mirror images are chiral.
Statement II: All chiral molecules have chiral centres.

Options

A. Statement I and II are true and Statement II is the correct explanation for Statement I.
B. Statement I and II are true, but Statement II is not the correct explanation of Statement I.
C. Statement I is true, Statement II is false.
D. Statement I is false, Statement II is true.

Answer

C

Explanation

Molecules having perpendicular dissymmetric plane are chiral molecules without having chiral centre.
For example, allenes of the type

are chiral although they do not have chiral centres.
