Answer 1

The number of stereoisomers are possible for a compound of the molecular formula $$\mathrm{CH}{\phantom{A}}_3-\mathrm{CH}=\mathrm{CH}-\mathrm{CH}(\mathrm{OH})-\mathrm{Me}$$ is 4.

Explanation:

$$\begin{array}{c}\mathrm{CH}{\phantom{A}}_3-\mathrm{CH}=\mathrm{CH}-\stackrel{\ast }{\mathrm{C}}\mathrm{HCH}{\phantom{A}}_3\\ \phantom{..............}|\\ \phantom{................}\mathrm{OH}\end{array}$$

It exhibits both geometrical as well as optical isomerism.

cis - R	cis - S
trans - R	trans - S
