In `NO_(3)^(-)` ion, the number of bond pairs and lone pairs of electrons on nitrogen atom are
Thinking process
To solve this sequence we must know the structure of `NO_(3)^(-)` ion i.e,

Then, cound the bond pairs and lone pairs of electron on nitrogen.

A

`2,2`

B

`3,1`

C

`1,3`

D

`4,0`

Text Solution

Verified by Experts

The correct Answer is:
D
d) In N-atom, number of valence electrons =5
Due to the presence of one negative charge, number of valence electrons = `5+1=6` one O-atom forms two bond (=bond) and two O-atom shared wigh two electrons of N-atom
Thus, 3 O atoms shared with 8 electrons of N-atom
`therefore` Number of bond pairs (or shared pairs) = 4
Number of lone pairs = 0
