In the reaction, `Po overset(-alpha)(to) Pb overset(-beta)(to) Bi`, if Bi belongs to group 15, to which group Po belongs?

Options

A. 13
B. 14
C. 15
D. 16

Answer

d

Explanation

`underset(16 "group")(._(84)Po^(209)) overset(-alpha)(to) underset(14 "group")(._(82)Pb^(205)) overset(-beta)(to) underset(15 "group")(._(83)Bi^(205))`
Thus, according to group displacement law, Po belongs to 16 group.
