use the periodic table to identify each of the following bonds as polar or nonpolar.\nc—cl\npolar\nnonpolar\n…

Explanation:

Step1: Recall electronegativity concept

Electronegativity is the ability of an atom to attract electrons in a chemical bond. In a bond, if there is a significant difference in electronegativity between the two atoms, the bond is polar. If the electronegativity difference is zero or very small, the bond is non - polar.

Step2: Analyze C - Cl bond

Carbon (C) has an electronegativity of approximately 2.5 and chlorine (Cl) has an electronegativity of approximately 3.0. The electronegativity difference $\Delta\chi=3.0 - 2.5=0.5$. Since there is a non - zero electronegativity difference, the C - Cl bond is polar.

Step3: Analyze Br - Br bond

Bromine (Br) atoms in a Br - Br bond have the same electronegativity (both Br atoms have an electronegativity of approximately 2.8). The electronegativity difference $\Delta\chi = 2.8-2.8 = 0$. So, the Br - Br bond is non - polar.

Answer:

C—Cl: polar Br—Br: nonpolar
