H NEHO N HN DR 0 R _ 16. Which of the following is the strongest type of interaction that occurs between the atoms within the circled areas of the two molecules represented above? A) Polar covalent bond B) Nonpolar covalent bond C) Hydrogen bond D) London dispersion forces
A covalent bond is a bond in which electrons are shared between atoms of elements
A covalent bond is a
bond in which electrons are shared between atoms of elements. A
covalent bond can be polar or nonpolar. In a nonpolar covalent
bond, the bond is between two identical atoms and the electrons are
evenly shared between the atoms.In contrast, in a
polar covalent bond, the bond is between two nonidentical atoms and
the electrons are unevenly shared between the atoms. The uneven
sharing of electrons takes place because of the difference in the
electronegativity...
