NEET levelSingle correct optionDifficulty 1 of 3pn093

The hybridisation of nitrogen in the nitrate ion, $NO X_{3} X^{-}$ , and its shape are

A $s p^{2}$ , trigonal planar
B $s p^{3}$ , pyramidal
C $s p$ , linear
D $s p^{3}$ , tetrahedral

Answer: A

NO X_{3} X^{-}

has three bond pairs and no lone pair on N, so N is

s p^{2}

hybridised and the ion is trigonal planar with three equal N-O bonds.
