The H-C-H, H-N-H, and H-O-H bond angles (in degrees) in methane, ammonia and water are respectively, closed to

Options

A. 109.5,104.5,107.1
B. 109.5,107.1,104.5
C. 104.5,107.1,104.5
D. 107.1,104.5,109.5

Answer

B

Explanation

Bond angle `109.5^@" " 107.1^@" " 104.5^@`
Order of repulsions `lp - bp gt bp - bp`, hence greater the no. of lone pairs smaller the bond angle
(If hybridization of central atom is same).
