Question

The correct order of increasing bond angle in following a) CH₄ (b) H₂O (c) H₂O (d) BF₃

Answer 1

Your answer is:

H₂O < CH₄ < BF₃

Bond angle in H₂O = 104.5

Bond angle in CH₄ = 109.5

Bond angle in BF₃ = 120

So, the above answer is right

Please mark me brainliest

Answer 2

Answer:

correct order is

H2O<CH4<BF3

options b and c are same.

Explanation:

•H2O is sp³ hybridised so the expected bond angle is 109° but due to presence of lone pair on oxygen (which causes repulsion) the bond angle decreases to 104°.

•C in CH4 has no lone pair so bond angle is 109°.

•BF3 is sp2 hybridised so bond angle is 120°
