Question

Which of the following molecule has largest bond angle?
a) H₂O
b) NH₃
c) CO₂
d) CH₄

Answer 1

option c is correct because
H2O form bend structure having 2 lone pairs over oxygen . it make angle of 104.5
NH3 form pyramidal structure having 1 lone pair . make angle of 107
CO2 form linear structure having no lone pair on carbon . make angle of 180
CH4 form tetra hedral structure having no lone pair .make angle of 109.5
so CO2 has largest bond angle
HOPE THIS WILL HELP YOU

Answer 2

Answer:

CO₂  has largest bond angle.

Explanation:

• CO₂ has greater bond angle.
• On the basis of the shape of CO₂ molecule is linear.
• It has sp hybridisation.
• So the bond angle will be 180°.
• In CO2, the carbon (C) atom has no lone pair and is connected to two oxygen (O) atoms.
• So no distortion occurs around the central atom which makes it linear in shape that has a bond angle of 180º.
