Number of bonding electron pairs and number of lone pairs of electrons in `ClF_(3)`,` SF_(4)`, `BrF_(5)`, respectively are

Options

A. 3, 2, 4, 2, 5,2
B. 3, 1, 4, 1, 5, 2
C. 3, 1, 4, 2, 5,1
D. 3,2, 4, 1, 5,1

Answer

(d)

Explanation

The valence electrons that are shared with another atom during chemical bond are known as bond pairs (bp) and which are not shared are known as lone pairs (p).
`CIF_(3): 3 (bp)`, 2(lp)
`SF_(3):4 (bp)`, 1 (lp)
`BrF_(3):5 (bp)`, 1 (IP)
