The hybridisatipon of atomic orbitals of nitrogen in `NO_(2)^(+),NO_(3)^(-)"and"NH_(4)^(+)` respectively are

A

`sp , sp^(3) and sp^(2)`

B

`sp, sp^(2) and sp^(3)`

C

`sp^(2) , sp and sp^(3)`

D

`sp^(2), sp^(3) and sp`

Text Solution

Verified by Experts

The correct Answer is:
B
`X = 1/2 (VE + MA - c + a)`
where, VE = No. of valence electrons on the central atom.
MA = No. of monovalent atoms surrounding the central atom.
c = Charge on the cation , a = Charge on the anion
For `NO_(2)^(+), X = 1/2 (5 + 0 - 1) = 2 ` (sp hybrid orbitals)
For `NO_(3)^(-), X = 1/2 (5 + 0 + 1) = 3 ` (`sp^(2)` hydrid orbitals)
For `NH_(4)^(+) , X = 1/2 (5 + 4 - 1) = 4` (`sp^(3)` hybrid orbitlas)
