Which of the following is not a pair of functional isomers?
1 $\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OC}_{2} \mathrm{H}_{5}$ and $\mathrm{C}_{3} \mathrm{H}_{7} \mathrm{OCH}_{3}$
2 $\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{OH}$ and $\mathrm{CH}_{3} \mathrm{OCH}_{3}$
3 $\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{NO}_{2}$ and $\mathrm{H}_{2} \mathrm{NCH}_{2} \mathrm{COOH}$
4 $\mathrm{CH}_{3} \mathrm{COOH}$ and $\mathrm{HCOOCH}_{3}$
Explanation:
$\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OC}_{2} \mathrm{H}_{5}$ and $\mathrm{C}_{3} \mathrm{H}_{7} \mathrm{OCH}_{3}$ is metamerism because it has change in no. of carbon present in parent chain. The other option given is show functional group isomer.

An organic compound is optically active if it
1 is planar
2 is super imposable on its mirror image
3 contains chiral centres
4 is non-super imposable on its mirror image.
Explanation:
The non-superimposable on its mirror image is optically active in nature. If the plane of symmetry (POS) or centre of symmetry (COS) is present then the molecule will be optically inactive.

Which of the compounds when brominated turns to meso 2, 3 di bromobutane?
1 Cis-2- butene
2 Iso butane
3 Butane
4 Trans- 2- butene
Explanation:
(D): The addition of bromine to an alkene is a stereo-specific reaction. It means that when a particular stereo Isomeric form of the staring material react in such a way that it gives a specific stereo isomeric form When trans-2-butene compound brominated turns to meso 2, 3 di bromobutane.

Spin isomerism is shown by
1 dichlorobenzene
2 hydrogen
3 dibasic acid
4 n-butane
Explanation:
Ortho in para hydrogen are spin isomers because they differ from each other in direction of the spin of their nuclei.
