Question

Consider the following statements:

(A) NF₃ molecule has a trigonal planar structure.

(B) Bond length of N₂ is shorter than O₂.

(C) Isoelectronic molecules or ions have identical bond order.

(D) Dipole moment of H₂S is higher than that of water molecule.

Choose the correct answer from the option below:

(1) (A) and (D) are correct
(2) (C) and (D) are correct
(3) (A) and (B) are correct
(4) (B) and (C) are correct

Answer 1

(4) (B) and (C) are correct

(A) NF₃ has trigonal Pyramidal shape.

(B) Bond order ⇒ N₂ > O₂

Bond length ⇒ N₂ < O₂

⇒ (C)

(D) Dipole moment H₂O > H₂S

Due to electronegativity difference.
