Select the correct statement(s) about nitric acid and the nitrate ion.

AIn $HNO X_{3}$ nitrogen is $s p^{2}$ hybridised
BIn $HNO X_{3}$ the N-OH bond is longer than the other two N-O bonds
CThe $HNO X_{3}$ molecule is planar
D $NO X_{3} X^{-}$ is pyramidal

Answer: A, B, C

HNO3 has N bonded to three O atoms with no lone pair on N:

s p^{2}

, planar. The N-OH single bond is longer than the two N-O bonds of partial double bond character. In

NO X_{3} X^{-}

the three N-O bonds are equal and the ion is planar, not pyramidal.
