Question

The number of stereoisomers are possible for a compound of the molecular formula \[\ce{CH3 - CH = CH - CH(OH) - Me}\] is ______.

Options

• 2

• 4

• 6

• 3

Answer 1

The number of stereoisomers are possible for a compound of the molecular formula \[\ce{CH3 - CH = CH - CH(OH) - Me}\] is 4.

Explanation:

\[\begin{array}{cc}\ce{CH3 - CH = CH - \overset{∗}{C}HCH3}\\\phantom{..............}|\\\phantom{................}\ce{OH}\end{array}\]

It exhibits both geometrical as well as optical isomerism.

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