- ✓$C{H_3}Cl$
- B$C{H_3}C{H_2}Cl$
- C${(C{H_3})_2}CHCl$
- D${(C{H_3})_3}C - Cl$
✓
Answer
Correct option: A.
$C{H_3}Cl$
a
(a) ${S_{{N^2}}}$ Substitution nucleophilic bimolecular order of different alkyl halides. ${1^o} > {2^o} > {3^o}$
(a) ${S_{{N^2}}}$ Substitution nucleophilic bimolecular order of different alkyl halides. ${1^o} > {2^o} > {3^o}$
${S_{{N^1}}}$ Substitution nucleophilic unimolecular order of different alkyl halides , ${3^o} > {2^o} > {1^o}$.
