Topic: JEE PYQ

Answer: A, B, C. Full step-by-step solution below.

A $B i_{2} O_{5} is more basic than N_{2} O_{5}$
B $N F_{3} is more covalent than B i F_{3}$
C $P H_{3} boils at lower temperature than N H_{3}$
D $The N-N single bond is stronger than the P-P single bond$

Correct answer: A, B, C

Solution

(a,b,c) \Rightarrow B i_{2} O_{5} is more basic than N_{2} O_{5} \Rightarrow N F_{3} is more covalent than B i F_{3} \Rightarrow N H_{3} boiling point is higher than P H_{3} \Rightarrow P-P single bond is stronger than N-N single bond.
