Consider the following statement

(A) NF3{NF}_{3} molecules has a trigonal planar structure.

(B) Bond Length of N2{N}_{2} is shorter than O2{O}_{2}.

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

(D) Dipole moment of H2S{H}_{2}S is higher than that of water molecule.

Choose the correct answer from the options given below:

Consider the following statement (A) NF _ 3 molecules has a trigonal planar structure. (B) Bond Length of N _ 2 isConsider the following statement (A) NF _ 3 molecules has a trigonal planar structure. (B) Bond Length of N _ 2 is

Options

  1. A(A)\left(A\right) and (B)\left(B\right) are correct
  2. B(A)\left(A\right) and (D)\left(D\right) are correct
  3. C(C)\left(C\right) and (D)\left(D\right) are correct
  4. D(B)\left(B\right) and (C)\left(C\right) are correct

Correct answer

D. (B)\left(B\right) and (C)\left(C\right) are correct

Step-by-step solution

In NF3{NF}_{3}, nitrogen is having three bond pairs and a lone pair, hence, it has pyramidal shape.

The bond order of N2=3,{N}_{2} = 3, and The bond order of O2=2{O}_{2} = 2. Bond length is inversely related to bond order. Hence, bond length of N2{N}_{2} is shorter than O2{O}_{2}

Isoelectronic species have identical bond order

Consider the following statement (A) NF _ 3 molecules has a trigonal planar structure. (B) Bond Length of N _ 2 is Consider the following statement (A) NF _ 3 molecules has a trigonal planar structure. (B) Bond Length of N _ 2 is

Dipole moment of H2O{H}_{2}O is more than that of H2S{H}_{2}S due to higher electronegativity of OO.
