Question

In which of the following N is in the $sp$ hybridisation state ?

• A. $(C{H}_3{)}_{3}N$
• B. $C{H}_{3}CON{H}_2$
• C. $N{O}_2^{+}$
• D. None of the above

Answer 1

The correct option is C $N{O}_2^{+}$

$S.N.=\frac{V+M-q+A}{2}$

M ⟶ Number of monovalent surrounding atoms
(H or halogens)

V ⟶ Number of valence electrons on central atom

q ⟶ Charge on cation

A⟶ charge on anion
S.N. = number of bond pair+number of lone pair
a) $(C{H}_3{)}_{3}N$
S.N.= 3+1=4
$s{p}^3$
b) $C{H}_{3}CON{H}_2$
S.N.= 3+1=4
$s{p}^3$
c) $N{O}_2^{+}$
$S.N.=\frac{V+M-q+A}{2}$
$S.N.=\frac{5+0-1+0}{2}$
$S.N.=2$
$sp$
