MCQ
Which of the following is better nucleophile
  • A
    $H_2O$
  • B
    $H{O^\Theta }$
  • ✓
    $OH^\Theta $
  • D
    $C{H_3}CO{O^\Theta }$
✓

Answer

Correct option: C.
$OH^\Theta $
c
If less electronegative atoms are attached to $O$, it is better nucleophile.. Hence $O H^\Theta $ is better nucleophile.
