What kind of isomerism is possible for 1chloro-2-nitroethene?
1 Functional group isomerism
2 Position isomerism
3 $\mathrm{E} / \mathrm{Z}$ isomerism
4 Optical isomerism
Explanation:
Isomerism is possible in 1-chloro - 2 - nitroethene. It show geometrical isomerism with naming $\mathrm{E} \& \mathrm{Z}$ If some priority group is present on same side then it is $\mathrm{Z}$ isomer and if it is present on opposite side then it is $\mathrm{E}$ isomer

Which of the following will have a meso-isomer also?
1 2-chlorobutane
2 2,3-dichlorobutane
3 2,3-dichloropentane
4 2-hydroxypropanoic acid
Explanation:
In the given compound 2,3-dichloropentane has two identical chiral center and plane of symmetry. The compound which contain more than one asymmetric center with superimposable mirror image and plane of symmetry such compound is called meso compound

Which are isomers?
1 Ethyl alcohol and dimethyl ether
2 Acetone and acetaldehyde
3 Propionic acid and propanone
4 Methyl alcohol and dimethyl ether
Explanation:
Isomers have the same molecular formula but different structure. Ethyl alcohol $\left(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}\right)$ and dimethyl ether $\left(\mathrm{CH}_{3} \mathrm{OCH}_{3}\right)$ both have the same molecular formula $\left(\mathrm{C}_{2} \mathrm{H}_{6} \mathrm{O}\right)$, so these are isomers.
