For each of the following pairs, identify which element tends to attract electron density from the other in a covalent bond and enter the four letters corresponding to these choices (e.g. ACEG, BDFH, etc.)

Question

A) O and B) C
C) O and D) H
E) Hg and F) C
G) Si and H) Cl

Does this have any thing to do with electronegativity?

Answer 1

It has EVERYTHING to do with electronegativity.
The more EN element will attract the electrons more so than the less EN one.
