Question

Which of the following bonds will be most polar?
(a) N – Cl
(b) O – F
(c) N – F
(d) N – N

Answer 1

(d)N-N is the correct answer.

Hope ut helped you.

Answer 2

Dear Student,

◆ Answer -

(C) N – F

● Explaination -

• Polarity of the bond depends upon the electronegativity difference between participating entities.
• Bigger the electronegativity difference, more polar is the molecule.
• Electronegativity difference in given compounds -

(a) N–Cl => 3-3 = 0

(b) O–F => 4-3.5 = 0.5

(c) N–F => 4-3 = 1

(d) N–N => 3-3 = 0

• As N-F molecule has bigger electronegativity difference, it will be most polar of all.

Thanks dear...
