Which of the following species has plane triangular shape
Options
(a) N₃
(b) NO₃⁻
(c) NO⁻₂
(d) CO₂
Correct Answer:
NO₃⁻
Explanation:
Hybridization of NO₃⁻=1/2 (5+0+1-0)
= 6/2=3=sp² hence geometry is trigonal planner.
NO₂⁻ (nitrate ion) also has sp² hybridization and gives a trigonal planner geometry but because there are only two outer atoms, the molecular geometry is bent with <120⁰ bond angles.
