Consider the following statement (A) NF 3 molecules has a trigonal planar structure. (B) Bond Length of N 2 is shorter than O 2 . (C) Isoelectronic molecules or ions have identical bond order. (D) Dipole moment of H 2 S is higher than that of water molecule. Choose the correct answer from the options given below:
Options
- AA and B are correct
- BA and D are correct
- CC and D are correct
- DB and C are correct
Correct answer
D. B and C are correct
Step-by-step solution
In NF 3 , nitrogen is having three bond pairs and a lone pair, hence, it has pyramidal shape. The bond order of N 2 = 3 , and The bond order of O 2 = 2 . Bond length is inversely related to bond order. Hence, bond length of N 2 is shorter than O 2 Isoelectronic species have identical bond order Dipole moment of H 2 O is more than that of H 2 S due to higher electronegativity of O .
