JEE · NEET Previous Year Question
The correct order of increasing bond angles in the following triatomic species is
Topic: NEET PYQ
Answer: B. Full step-by-step solution below.
- ANO2– < NO2+ < NO2
- BNO2– < NO2 < NO2+
- CNO2+ < NO2 < NO2–
- DNO2+ < NO2– < NO2
Correct answer: B
Solution
(b) The order of repulsion of electrons is : lp–lp repulsion > lp–bp repulsion > bp–bp repulsion Higher the number of lone pair of electrons (greater is repulsion) lower is the bond angle and vice-versa. In NO2– one lone pair of electron is present while in NO2+ no lone pair of electron is present. Hence, the correct order of bond angles is NO2– < NO2 < NO2+More Chemical Bonding PYQs
