The number of electrophiles and nucleophiles present in the species given below are respectively.
`BF_(3), CO_(2), Me_(3)N, SO_(3), CH_(3)overset(+)(CO), HS^(-), NO_(2)^(+), FeCl_(3), H_(2)O`

Options

A. 6, 3
B. 3, 6
C. 4, 5
D. 5, 4

Answer

A

Explanation

`BF_(3)` - Electrophile, `CO_(2)` - Electrophile,
`Me_(3)N` - Nucleophile, `SO_(3)` - Electrophile,
`overset(+)(CH_(3)CO)` - Electrophile, `HS^(-)` - Nucleophile,
`NO_(2)^(+)` - Electrophile, `FeCl_(3)` - Electrophile,
`H_(2)O` - Nucleophile,
So, total number of electrophiles = 6
Total number of nucleophiles = 3
