Question

Statement I Molecules that are non-superimposable on their mirror images are chiral.
Statement II All chiral molecules have chiral centres.
(1) Statement I is correct; Statement II is correct; Statement II is the correct explanation of Statement I
(2) Statement I is correct; Statement II is correct; Statement II is not the correct explanation of Statement I
(3) Statement I is correct; Statement II is incorrect
(4) Statement I is incorrect; Statement II is correct

Answer 1

Molecules that are non-superimposable on its mirror image are optically active and known as chiral molecule. However, for chirality of molecule, presence of chiral centre is not essential,
e-g.
Molecule is chiral but does not possesses any chiral carbon.
