Species having X-O-H linkage (X=non-metal with positive oxidation state) are called oxy acids and parent acid of a non-metal may exist in two form (a)-ic form of parent oxy acid (b)-us form parent oxy acid.
Q. Number of P-O bond(s) having bond order=2, in `P_(2)O_(6)^(4-)` ions is:

Options

A. 0
B. 2
C. 3
D. 6

Answer

A

Explanation

Inert pair effect phenomenon is exclusively applicable to sixth period elements belonging to 13, 14 and 15th group elements.
Due to inert pair effect `Pb^(2+)` is more stable than `Pb^(4+)`.

Hence, `Ti^(+)` does not act as reducing agent.
`ln^(+) to ln^(3+)+2e^(-)`
Hence, `ln^(+)` can act as stronger reducing agent than `Ti^(+)`.
