Giving justification, categorise the following moelcules/ions as nucleophile or electrophile:
`HS^(-),BF_(3),C_(2)H_(5)O^(-),(CH_(3))_(3)N`:
`Coverset(+)(l),CH_(3)-overset(+)(C)=O,H_(2)Nbar:,overset(+)(N)O_(2)`

Text Solution

Verified by Experts

Nucleophiles: `HS ^(-) , C _(2) H _(5) O ^(-), (CH _(3)) _(3) N: , H _(2) N :` These species have unshared pair of electrons, which can be donated and shared with an electrophile.
Electrophiles: `BF _(3), overset(+)(Cl) , CH _(3) - overset(+) (C) = O, overset(+)(N) O _(2).`
Reactive sites have only six valence electrons, can accept electron pair from a uncleophile.
