Answer» Correct Answer - A Because the `pi` bond results from overlapping `p` orbitals, the `pi` electrons lie above and below the plane of the double bond. Therefore, the electrons of the `pi` bonds are exposed and susceptible to electron-seeking reagents called electrophiles. Electrophiles include positive reagents such as protons `(H^(+))`, neutral reagents such as bromine ( beacuse it can be polarized so that one end is positive), and the Lewis acids such as `AlCl_(3)` and `BF_(3)`. Metal ions containing vacent orbitals such as silver as silver ion `(Ag^(+))`, mercuric ion `(Hg^(2+))`, and platinum ion `(Pt^(2))` also act as electrophiles. |
