THE FORMATION OF A BOND BETWEEN HYDROGEN AND A HIGHLY ELECTRONEGATIVE ATOM RESULTS IN

• A. polarity ✓
• B. electrovalent bond
• C. dipole
• D. metallic bond

When hydrogen forms a bond with a highly electronegative atom such as nitrogen (N), oxygen (O), or fluorine (F), it results in polarity. This is because the highly electronegative atom attracts the shared pair of electrons more strongly than hydrogen, leading to an uneven distribution of charge within the molecule. The electronegative atom will have a partial negative charge, while the hydrogen atom will have a partial positive charge, creating a dipole moment in the molecule.

In other words, when a bond forms between hydrogen and a highly electronegative atom, it results in polarity. Polarity refers to the uneven distribution of electrons in a chemical bond due to differences in electronegativity between the atoms involved. In the case of hydrogen bonding with a highly electronegative atom, such as oxygen or fluorine, the shared electrons are pulled closer to the more electronegative atom, creating a partial negative charge on that atom and a partial positive charge on the hydrogen atom. This unequal sharing of electrons leads to the formation of a polar covalent bond.
