CH3 - CH2 - CH = CH2 + HBr 
 X (major) + Y (minor)

X and Y are
  • a)
    BrCH2 - CH2 - CH = CH2 and C2H5 - CHBr - CH3
  • b)
    C2H5 - CH2 - CH2Br and Br - CH2 - CH2 - CH = CH2
  • c)
    C2H5 - CH2 - CH2Br and C2H5 - CHBr - CH3
  • d)
    C2H5CHBr - CH3 and C2H5 - CH2 - CH2Br
Correct answer is option 'C'. Can you explain this answer?

CH3- CH2- CH = CH2+ HBrX (major) + Y (minor)X and Y area)BrCH2- CH2- C...
According to anti-Markovnikov's rule, X is 1-bromobutane and Y is 2-bromobutane.

In this reaction, organic peroxide dissociates butene into free radicals. There is the formation of free radicals as intermediates.

More stable free radicals give major products according to anti-Markovnikov's rule.
