MCQ

Consider the following statements:

$(A)$ $NF _3$ molecule 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 option below:

A
$(A)$ and $(D)$ are correct
B
$(C)$ and $(D)$ are correct
C
$(A)$ and $(B)$ are correct
✓
$(B)$ and $(C)$ are correct

✓

Answer

Correct option: D.

$(B)$ and $(C)$ are correct

d
$(A)$ $NF _3$ has trigonal pyramidal shape.

$(B)$ Bond order $\Rightarrow N _2 > O _2$

$(D)$ Dipole moment $H _2 O > H _2 S$

Due to Electronegativity difference.
