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
(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
Show Hint
Isoelectronic species have the same number of electrons and bond orders
- (A) and (D) are correct
(B) and (C) are correct
- (A) and (B) are correct
(C) and (D) are correct
The Correct Option is B
Solution and Explanation
Statement Analysis:
- (A): Incorrect—NF3 has a trigonal pyramidal structure due to the lone pair on the nitrogen atom, not a planar structure.
- (B): Correct—N2 has a triple bond, resulting in a shorter bond length compared to O2, which has a double bond.
- (C): Correct—Isoelectronic species such as O2−, F−, and N2 have identical bond orders because they share the same number of electrons and similar electronic configurations.
- (D): Incorrect—Water (H2O) has a higher dipole moment due to the bent geometry and the high electronegativity of oxygen, whereas NF3 has a lower dipole moment due to the partial cancellation of dipoles in its pyramidal structure.
Conclusion:
Correct Statements: (B) and (C).
Incorrect Statements: (A) and (D).
