Question

identify the correct dipole for the c$-$br bond in the lewis structure of methyl bromide shown using a vector arrow.
i
ii
iii
iv

Explanation:

Dipole arrows point from the less electronegative atom to the more electronegative atom. Bromine (Br) is more electronegative than carbon (C), so the arrow should start at C and point toward Br, with the positive end (+) on C and the arrowhead on Br.

Answer:

II. $\ce{H - \underset{\underset{H}{|}}{C} - H}$ with arrow pointing from C to Br (positive end on C, arrowhead on Br)
