Question

How many bond pairs and lone pairs does CO2 have?

Answer 1

HI mate GM here is your answer....,

Each oxygen contributes 2 electrons and 1 for each bond. That means there are a total of 8 electrons around the carbon, in 4 pair. Because there are 4 bonds, these are all bond pairs. Each double bond uses 2 bond pair which are then thought of as a single unit. There is no lone pair in Co2

I hope it will help you and mark me as a brain list answer plz.

Answer 2

The bond pairs and lone pairs of $CO_{2}$ can be found by finding the number of electron pair around the central atom

Number of electron pair around the central atom = $\frac{1}{2} (V+M-C+A)$

where

V= Number of valence electron of the central atom

M= Number of monovalent atom around the central atom

C= Cationic charge

A= Anionic charge

In this case

V=2(Two valence electron in the outer shell of carbon atom)

M=2 (Two monovalent oxygen atoms are there)

Number of electron pair around the central atom (here C) = $\frac{1}{2} (2+2)$ =2

From the below image given it can be seen that the 2 bonds of CO₂ are involved in two C-O bonds and no other bonds are there.

Hence there are 2 bond pairs in CO₂ and no lone pairs are there.
