Question

The number of lone pair of electrons on the central atoms of $H_2O,\, SnCl_2,\, PCl_3$ and $XeF_2$ respectively, are

• A. 2, 1, 1, 3
• B. 2, 2, 1, 3
• C. 3, 1, 1, 2
• D. 2, 1, 2, 3

Answer 1

Answer: (A)

2, 1, 1, 3

Answer 2

The number of lone pairs of electrons on the central atoms of $H _{2} O , SnCl _{2}, PCl _{3}$ and $XeF _{2}$ are $2 , 1, 1$ and $3$ respectively.

Number of lone pairs = 2

Number of lone pair = 1

Number of lone pair = 1

Number of lone pairs = 3.
