1.

Select thecorrect order sequence(s).

Answer»

`C-C` bond length :
Order of dipole moment : `COgtNH_(3)`
Boiling POINT : `AsH_(3)gtNH_(3)`
Bond order of `M-O` bond (M = CENTRAL atom) : `CO_(3)^(2-)gtPO_(4)^(-3)`

Solution :(d) B.O. : `CO_(3)^(2-)=(4)/(3),PO_(4)^(3-)=(5)/(4)`
(c) B.P. : `BiH_(3)gtSbH_(3)gtNH_(3)gtAsH_(3)gtPH_(3)`
