Addition of HX on alkene proceed through formation of carbocation . This reaction is follows Markovnikov's rule. According to markovnikov's rule addition of electrophile occurs on that carbon of alkene which have more number of -H atom
`Ph-CH = CH_2 underset(HX)to underset("(major)")(Ph-overset(x)overset(|)CH-CH_3) + underset("(minor)")(Ph-CH_2-CH_2-X)`
Which of the following alkenes can produce diastereomers

Options

A. `CH_3-CH=CH-CH_3`
B.
C.
D. `CH_3-CH=CH_2`

Answer

C

Explanation

Optically inactive alkene does not produces diastereomers on addition of HX Optically active alkenes produce diastereomers if a chiral carbon in generated uring addition
A) Is not optically active
B) is not optically active
C) Is optically active D) Is not optically active
