What is the electronegativity difference for the compound CH2O, is the compound symmetrical or asymmetrical, and is the compound polar, nonpolar, or ionic?

axie:

You got any answer choices?

@kekeman

axie:

If that helps ;-;

kekeman:

No i do not have any answer choices

kekeman:

What is the electronegativity difference?

axie:

@vocaloid

Vocaloid:

CH2O consists of one carbon atom, double bonded to oxygen. The carbon atom also contains two single bonds, one to each hydrogen. So for the electro negativity difference, look up the electro negativity values for C, H, and O to calculate the electro negativity difference for 1. The C=O bond And 2. The two C-H bonds

So add the electronegativity of oxygen which is 3.44 and of carbon which is 2.55 to get 5.99 then subtract it by the electronegativity of hydrogen which is 2.20 to get 3.79?

kekeman:

Or do i just have to subtract 3.44 - 2.55 - 2.20 = -1.31

Vocaloid:

You cannot subtract them all together because they represent separate bonds I would just calculate 1. For C=O, the difference between C and O And 2. For C-H, the difference between C and H

Vocaloid:

For step 1, the C=O calculate the difference between C and O In a completely separate calculation, for step 2) calculate the difference between the C and the H

kekeman:

Ok so 0.89 because 3.44 - 2.55 0.89 is the difference

Vocaloid:

Good, that’s for C=O Repeat for CH

kekeman:

Then 0.35 for the difference for CH

Vocaloid:

Good. It doesn’t really make sense to combine these numbers together, so I would report the electro negativity difference for both bonds

So we would not just subtract 0.89 from 0.35 to get 0.54? Or just report the electro negativity difference for both bonds?

i need help

Vocaloid:

It doesn’t make sense to subtract the numbers because they come from different bonds. I would personally just report both numbers.

kekeman:

Ok thank you for the help

kekeman:

Wait is it symmetrical or asymmetrical, and is the compound polar, nonpolar, or ionic?
