232245 The correct relationship between molecules I and $\mathrm{II}$ is
1 Enantiomer
2 Homomer
3 Diastereomer
4 Constitutional isomer
Explanation:
The correct relation ship between I and II is Homomer or identical From the above we can say that both are homomer. If molecule get rotation and comes to original compound then such compound in called homomer of each other. It is also minor image of each other.

Which of the following will exhibit cis-trans isomerism
In cis-trans isomer compound has restricted rotation around double bond and substituent attached to alkene is different If any one $a=c \& b=d$ then we use cis-trans namings a) $\mathrm{CH}_{2}-\mathrm{Br}-\mathrm{CH}_{2}-\mathrm{Br} \rightarrow$ It does not have restricted rotation It also does not have flertricted rotation It show cis trans isomer The substituent attached to alkene is sume so it not show cis-trans isomer

The two structures written below represent:
1 pair of diastereomers
2 pair of enantiomers
3 same molccule
4 both are optically inactive
Explanation:
The two structure is given are same molecules or Homomer Homomer- It is a super imposable mirror image with one Asymmetric center After rotating we get superimposable mirror image a bid same as [1] molecule Hence we can say that I \& II molecule are identical.

The correct statement regarding the following compounds is
1 all three compounds are chiral
2 only I and II are chiral
3 I and III are diastereomers
4 only I and III are chiral
Explanation:
Exp : (D) : **Plane of symmetry-** It is an imaginary line passing through molecule bisecting in two equal parts which is mirror image of each other. In II has plane of summery so it is achiral and optically inactive. But In I and III it does not have any plane of symmetry so it is chiral
232245 The correct relationship between molecules I and $\mathrm{II}$ is
