identify the functional group and indicate polar bonds by assigning partial positive and negative charges.

1) The structure CH3OCH3 is drawn out and I know that this is an ether because the O is bonded to two carbons but I am not sure how to assign the charges. I think that the oxygen would be negative and the two C's would be positive but I am not sure.

Would you agree with my answer?

This looks much like the HOH molecule/
O-H

H. Of course you know both H atoms are partially positive and O is partially negative. Same with ethers.

O-CH3
|
CH3
O is partially negative; the two C atoms are partially positive.
