Which of the following compounds is asymmetric?
1
2
3
4
Explanation:
Those compound having plane of symmetry and super imposable mirror image that compound is said to achiral and it is also called symmetric molecule. For Asymmetric molecule it have chiral center and no plane of symmetry and center of symmetry. Option (d) does not have plane of symmetry as well as center of symmetry so it is chiral or Assymetric.

The incorrect statement regarding chirality is
1 The product obtained by $\mathrm{S}_{\mathrm{N}} 2$ reaction of haloalkane having chirality at the reactive site shows inversion of configuration.
2 Enantiomers are superimposable mirror images on each other.
3 A racemic mixture shows zero optical rotation.
4 $\mathrm{S}_{\mathrm{N}} 1$ reaction yields $1: 1$ mixture of both enantiomers.
Explanation:
The stereoisomers related to each other an non-superimposable mirror image are called enantiomers.
