School and Work: bonds

Open Question: is there a way to count polar bonds given chemical formula only?

for example :C21 H28 O2

i mean without drawing a lewis structure

Sorry, I could not read the content fromt this page.

This is really though but im going to have to say that they are strong bonds is wrong.
I dont think they have strong bonds.

hope i helped

choose as best answer

I-F is first - All you need to do is look at electronegativity for polarity

I is less electronegative than Br so it does not pull the electron density as much as bromine would.

Because F is the most electronegative, more electron density is towards the F when the other atom is less electronegative

And Br-Br is last because the electron density is shared equally

the sheets are a hexagonal pattern of covalent bonds - the valency is satified.

between sheets iare no covalent bonds just London forces
