NEET 2026 — Chemistry solution

NEET2026Chemistry

Identify the incorrect statement from the following:

A
Phosphorus, arsenic and antimony show catenation property
B
P(C $_{2}$ H $_{5}$ ) $_{3}$ and As(C $_{6}$ H $_{5}$ ) $_{3}$ form d $π$ -d $π$ bond with transition metals
C
Nitrogen can form d $π$ -p $π$ bond with oxygen
D
Nitrogen can form p $π$ -p $π$ multiple bonds with itself.

Solution

Both N and O are second-period elements and lack d-orbitals. Therefore they can only form p $π$ -p $π$ bonds with each other, not d $π$ -p $π$ bonds. Hence statement (3) is incorrect.
