MCQ
In each of the following groups, which is the strongest (best) nucleophile ?
  • A
    $I-3 \,;\, II-3 \,;\,  III-2$
  • B
    $I-2 \,;\, II- 1 \,;\, III-3$
  • $I-1\,;\, II-2 \,;\, III-1$
  • D
    $I-3 \,;\,  II-1 \,;\,  III-3$

Answer

Correct option: C.
$I-1\,;\, II-2 \,;\, III-1$
c
If $-ve$ charge is present at same atom in defferent nucleophiles then

Nucleophilicity $ \propto $ $1$ $/$ Acidic strength of conjugate acid
