Question

the species in which the N atom is in a state of sp hybridisation is a) NO2+ b) NO2 c) NO2-​

Answer 1

Answer:

$a) NO_2 {}^{ + }$

Explanation:

Nitrogen has 5 valence electrons in outer most cell .

$\frac{1}{2} (v + m + a - c) \\ \\ v = valence \: shell \: electron \\ m = monovalent \: atom \\ a = anion( - ve \: charge) \\ c = cation \: ( + ve \: charge) \\ \\ \frac{1}{2} (5 + 0 + 0 - 1) \\ \\ \frac{1}{2} (4) \\ \\ = 2 \\ \\ sp \: hybridisation$

Answer 2

Answer:

$NO _{2} {}^{ + }$
