Solution

Solution Steps

Step 1: Determine the Polarity of the $\ce{Cl-Cl}$ Bond

The bond between two chlorine atoms ($\ce{Cl-Cl}$) involves two identical atoms. Since both atoms have the same electronegativity, the electrons are shared equally, making the bond nonpolar.

Step 2: Determine the Polarity of the $\ce{H-Cl}$ Bond

The bond between hydrogen and chlorine ($\ce{H-Cl}$) involves atoms with different electronegativities. Chlorine is more electronegative than hydrogen, so the electrons are more attracted to the chlorine atom, making the bond polar. The chlorine atom will have a more negative charge.

Step 3: Determine the Polarity of the $\ce{I-I}$ Bond

The bond between two iodine atoms ($\ce{I-I}$) involves two identical atoms. Since both atoms have the same electronegativity, the electrons are shared equally, making the bond nonpolar.

Final Answer

$\ce{Cl-Cl}$: The highlighted bond is nonpolar. $\boxed{\text{The highlighted bond is nonpolar}}$
$\ce{H-Cl}$: The highlighted bond is polar and the more negative atom is $\boxed{\ce{Cl}}$.
$\ce{I-I}$: The highlighted bond is nonpolar. $\boxed{\text{The highlighted bond is nonpolar}}$
