Question

Will someone check my answer?
CO2
1. What is the central atom?
C
2. How many atoms are bonded to the central atom?
2 oxygens
3. How many lone pairs of electrons are on the central atom?
None
4. How many single bonds are there in this molecule?
2
5. How many multiple bonds (double and/or triple) are there in this molecule
I don't know

Answer 1

Answer 2

I believe that you are correct... If not have you draw out the lewis structure for CO2?

Answer 3

I agree with you on 1, 2, and 3.

Answer 4

O=C=O

Answer 5

What did I do wrong with 4? And I really don't know 5.

Answer 6

Drawing out the Lewis structure would be helpful. If the bonds were single bonds, the C would have a lone pair and a partially full valence shell.

Answer 7

I drew it out, that was part of the assignment. I'm just confused. I'm not good with this stuff

Answer 8

Or maybe i Should say \(\sf \color{Red}{:ö=c=ö:}\)

Answer 9

I just don't know what single and multiple bonds are?

Answer 10

A single bond means each atom shares 1 electron, making the bond consist of 2 electrons.

Answer 11

A double bond means each atom shares. 2 electrons, making the bond consist of 4 electrons.

Answer 12

A triple bond means each atom shares 3 electrons, making the bond consist of 6 electrons.

Answer 13

So the answer to 4 is not 2?

Answer 14

Right.

Answer 15

Than I am so confused

Answer 16

In order for C and O to have full valence shells (electrons each), the bonds would have to be double bonds.

Answer 17

So is the answer none?

Answer 18

Right.

Answer 19

Okay and is that the same for 5?

Answer 20

No, the bonds are double bonds, so there would be 2.

Answer 21

OH I GET IT NOW!

Answer 22

O::C::O

Answer 23

Awesome! :)

Answer 24

The oxygen atoms on my drawing have 2 lone pairs each.
