Pick out the incorrect statement

Options

A. Red phosphorus consists of a complex chain structure and black phosphorus has a layer structure
B. Nitrogen shows a little tendency for catenation, because `N-N` single bond is very strong.
C. The maximum number of covalent bonds formed by nitrogen is four, since it has no `d`-orbitals in its valence shell.
D. The group `15` elements do not form `M^(+5)` ions, but `+5` oxidation state is realized only through covalent bonding

Answer

B

Explanation

Catenation `prop 1//size`
`N` has more catenation tendency due to is small size. `Sb` and `Si` doesn't have catenation tendency.
