Answer

Explanation:

Step1: Recall electronegativity concept

Electronegativity determines bond polarity. If two atoms have the same electronegativity, the bond is non - polar. If different, the more electronegative atom is more negative.

Step2: Analyze Cl - Cl bond

Chlorine atoms in Cl - Cl have the same electronegativity. So, the bond is non - polar.

Step3: Analyze N - H bond

Nitrogen (N) has an electronegativity of 3.04 and hydrogen (H) has 2.20. N is more electronegative. So, the N - H bond is polar and the more negative atom is N.

Step4: Analyze H - Br bond

Bromine (Br) has an electronegativity of 2.96 and hydrogen (H) has 2.20. Br is more electronegative. So, the H - Br bond is polar and the more negative atom is Br.

Answer:

  1. The highlighted bond is nonpolar.
  2. The highlighted bond is polar and the more negative atom is N.
  3. The highlighted bond is polar and the more negative atom is Br.
