Question

VA group elements form tri oxides and pentoxides of the type `M_(2)O_(3)` and `M_(2)O_(5)` respectively (M-VA group element). The trioxides and pentoxides of nitrogen are monomers and that of P,As,Sb are dimers. Nitrogen forms various oxides ranging from `NO` to `N_(2)O_(5)`. Oxides of phosphorous have cage like stuctures.
Number of P-O-P bonds in `P_(4)O_(10)`:
A. 6
B. 4
C. 2
D. zero

Answer 1

Correct Answer - D
`N_(2)O_(5): sigma` bonds `=6,pi` bonds =2 number of lone pairs =12
`P_(4)O_(6):`Number of P-O-P bonds = 6
