Correct Answerc

5

Detailed Solution

Identifying Nucleophiles Nucleophiles are species that have a lone pair of electrons or a π\pi bond that can be donated to an electrophile.image Evaluating Other Species

  • \ceH3O+\ce{H3O^+}: Electrophile (positive charge, no lone pair to donate).
  • \ce(CH3)2CO\ce{(CH3)_2CO} and \ce>C=NCH3\ce{>C=NCH3}: Electrophilic at the C-atom. Total count = 5.
