Would it be Cl? since its closer to the right

By the rules of the forum, you must show your attempt at a problem, before anyone will help you.

Well, what does the electronegativity table say?

[Ander08]

well, for a) the answer would be CH3-Cl, because the Cl-Cl molecule would have equal polarity in both directions. and for b) i believe CH3-OH would be the answer because oxygen is a strong electron withdrawing atom, making the OH end have a greater negative charge.

Hi so does this look right?

[EDTA]

The arrows should be pointed at the direction of the elements that are more electronegative.

[Jessica508]

Thanks, so would it be correct since C₃C is more electronegative than Cl, HO is more electronegative than CH₃ and (H₃C)₃Si is more electronegative than CH₃ right? Also for Cl--Cl did I do the arrows correct?

No

HO is more electronegative than CH₃

Yes

(H₃C)₃Si is more electronegative than CH₃ right? Also for Cl--Cl did I do the arrows correct?

No.

You are suggesting that electronegativity of Si>C>Cl, which is incorrect. Google electronegativity and check the values.
