Addition of HX on alkene proceed through...

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 will give markovnikov's reaction ?

A

`F_3 C - CH = CH_2 overset(HCl)to`

B

`H_3N^(+)-CH = CH_2 overset(HCl)to `

C

`O_2N - CH = CH_2 overset(HBr)to`

D

Text Solution

Verified by Experts

The correct Answer is:
D
A) Because `F_3C- overset(oplus)(C)H-CH_3` is unstable due to powerful - I effect of `CF_3` group
B) `H_3^(oplus)N - CH - CH_2 overset(HCl)to H_3 overset(oplus)N -CH_2 - Cl`.
Because `NH_3 -CH-CH_3` unstable due to powerful - I effect of `NH_3` group
C) `NO_2 - CH - CH_2 NO_2 - CH_2 - Br `
Because `NO_2 - overset(oplus)CH_2 - CH_3` is unstable due to -I effect to `NO_2` group
D)
is more stable I effect `-CH_3` groups and .9. hypen conjugative structures
