Question

what is the overall polarity of this molecule? polar nonpolar

Explanation:

To determine molecular polarity, we consider the electronegativity difference between atoms and molecular geometry. In \(AsH_3\), arsenic (\(As\)) has a higher electronegativity than hydrogen (\(H\)). The molecule has a trigonal pyramidal geometry due to the lone pair on \(As\). This geometry causes the bond dipoles (from \(H\) to \(As\)) not to cancel out.

Answer:

polar
