Question

unit 1 - challenge 1.2: the chemical level
which of the following bonds is defined by atomic attraction where electrons are unequally shared between atoms?
a.) polar covalent bonds
b.) hydrogen bonds
c.) ionic bonds
d.) nonpolar covalent bonds

Explanation:

• Polar covalent bonds occur when atoms share electrons unequally due to differences in electronegativity.
• Hydrogen bonds are weak attractions between molecules, not atomic bonds with electron sharing.
• Ionic bonds involve the transfer of electrons, not sharing.
• Nonpolar covalent bonds have equal electron sharing.

Answer:

A. Polar covalent bonds
