$\mathop {C{H_3} - }\limits_a \mathop {C{H_2} - }\limits_b \mathop {C{H_2} - }\limits_c \mathop {C{H_2} - }\limits_d F$

Arrange the hydrogens $a, b, c, d$ in decreasing order of their reactivities towards chlorination

  • A
    $a > b > c > d$
  • B
    $b > c > d > a$
  • $b > c > a > d$
  • D
    $c > b > a > d$

Answer

Correct option: C.
$b > c > a > d$
c
$(c)$ Selectivity of $Cl \to 3^o > 2^o > 1^o$ hydrogen.
as well as $-I$ of $F$ -atom.
