The number of geometrical isomers of $\mathrm{CH}_{3}-\mathrm{CH}=\mathrm{CH}-\mathrm{CH}=\mathrm{CH}-\mathrm{CH}=\mathrm{CHCl}$ is
1 2
2 4
3 6
4 8
Explanation:
(D) : $\mathrm{CH}_{3}-\mathrm{CH}=\mathrm{CH}-\mathrm{CH}=\mathrm{CH}-\mathrm{CH}=\mathrm{CHCl}$ The given structure has three double bond whose carbon atom is differently subsituted. Hence number of geometrical isomer will be $2^{\mathrm{n}}=2^{3}=8$ Where $\mathrm{n}=$ no. of double bond

The following two compounds are are
1 enantiomers
2 diastereomers
3 identical
4 epimers
Explanation:
(A) : Both compound have chiral center with nonsuperimposable mirror image. Hence it is enantiomer.

Which of the following has two stereoisomers?
1 None of these
2 Only I
3 Only III
4 I and III
Explanation:
Only I has two stereoisomers. This includes a pair of enantiomer. Geometrical isomerism is not possible as two same atom (H-atoms) are attach to double bonded C-atoms. No stereoisomer are possible in II as two same groups (methyl groups) are attached to $\mathrm{N}$-atom. A rapid umbrella type inversion rapidly converts the structure III to its enantiomer. Hence two enantiomer are not separable.
