B

`B_(4)C`

C

`B_(2)H_(6)`

D

`BN`

Text Solution

Verified by Experts

The correct Answer is:
D
Boron nitride `(BN)` is a white slippery solid. One `B` atom and one `N` atom together have the same number of valence electrons as two `C` atoms. Thus, `BN` has almost the same structure as graphite, with sheets made up of hexagonal rings of alternate `B` and `N` atoms joined together. The sheets are stacked one on top of the other, giving a layer structure.
