Question

Refer to Figure 12.9, in the following polar covalent bonds which atom would be labeled with the δ+ (delta positive) and which atom would be labeled with the δ- (delta negative) notation.   The Electronegativities of several elements are below.

H = 2.1	C = 2.5	N = 3.0	O = 3.5	F = 4.0
	Si = 1.8	P = 2.1	S = 2.5	Cl = 3.0
		As = 2.0	Se = 2.4	Br = 2.8
			Te = 2.1	I = 2.5

-       a.       b.    The Carbon atom in the C - H bond would be labeled with       -       a.       b.    The Hydrogen atom in the C - H bond would be labeled with       -       a.       b.    The Selenium atom in the Se - O bond would be labeled with       -       a.       b.    The oxygen atom in the Se - O bond would be labeled with       -       a.       b.    The phosphorus atom in the P - I bond would be labeled with       -       a.       b.    The iodine atom in the P - I bond would be labeled with       -       a.       b.    The hydrogen atom in the H - Br bond would be labeled with       -       a.       b.    The Bromine atom in the H - Br bond would be labeled with
