Question

Explain Markovnikov rule taking a suitable example

Answer 1

Dear Student,

Markovnikov's rule states that : when H-X adds across the double bond of an alkene, the H atom becomes attached to the C atom that has the larger number of H atoms already attached.
Eg. when propene reacts with hydrogen bromide, Br gets attached to the C with less H atom while H gets attached to C with more H atom giving 2-bromopropane as the product.
${\mathrm{CH}}_3-\mathrm{CH}={\mathrm{CH}}_2+\hspace{0.17em}\mathrm{HBr}\to {\mathrm{CH}}_3-\mathrm{CH}\left(\mathrm{Br}\right)-{\mathrm{CH}}_3$
