Question
Explain why HBr is a polar molecule, but H2 and Br2 are not.
Answers
GPT 3.5
HBr is a polar molecule because it contains a polar covalent bond between the hydrogen (H) and the bromine (Br) atoms. A polar covalent bond is formed when there is a significant difference in electronegativity between the two atoms involved in the bond. In the case of HBr, bromine is more electronegative than hydrogen, meaning it has a higher affinity for electrons.
As a result, the shared electron pair in the H-Br bond is more strongly attracted towards bromine, giving it a partial negative charge (δ-) and leaving hydrogen with a partial positive charge (δ+). This uneven distribution of charge creates a dipole moment in the molecule, making HBr polar.
On the other hand, H2 and Br2 are not polar molecules because they consist of identical atoms bonded together. In these diatomic molecules, the electronegativity difference between the atoms is negligible or essentially zero. This means that the electron pair in the bond is shared equally between the atoms, resulting in no partial charges. As a result, there is no dipole moment in H2 and Br2, making these molecules nonpolar.

Certainly!
HBr is a polar molecule because the electrons in the bond between hydrogen and bromine are not shared equally. Bromine attracts the electrons more strongly, creating a partial negative charge (δ-) on the bromine atom and a partial positive charge (δ+) on the hydrogen atom. This uneven charge distribution makes HBr a polar molecule.
In contrast, H2 and Br2 are not polar molecules because they consist of identical atoms bonding together. Since the atoms have the same electronegativity, the electrons in the bond are shared equally. This equal sharing of electrons creates no partial charges and no dipole moment, making H2 and Br2 nonpolar.

Certainly! Here's a simpler explanation:
HBr is polar because the bromine atom attracts electrons more strongly than the hydrogen atom, creating a partial positive and a partial negative end in the molecule.
However, H2 and Br2 are not polar because they consist of identical atoms that share electrons equally. This equal sharing leads to no partial charges or a "tug-of-war" situation, making them nonpolar.
