Solution By Steps

Step 1: HBr Molecule Polar or Nonpolar

HBr is a polar molecule. Bromine is more electronegative than hydrogen, causing an uneven distribution of electrons and creating a net dipole moment.

Step 2: Atom Closest to Negative Side

In the HBr molecule, the bromine atom is closest to the negative side due to its higher electronegativity compared to hydrogen.

Final Answer

HBr molecule is polar, and the bromine atom is closest to the negative side.

Key Concept

Polarity

Key Concept Explanation

Polarity in a molecule arises from the difference in electronegativity between its constituent atoms. This results in an uneven distribution of electrons, leading to a net dipole moment. Understanding polarity is crucial in predicting a molecule's behavior in various chemical reactions and its interactions with other substances.
