Question

what is the similarities of polar covalent bonds and nonpolar covalent bonds​

Answer 1

$\huge\red{\fbox{\tt{ᴀɴsᴡᴇʀ}}}$

Polar covalent bonding is a type of chemical bond where a pair of electrons is unequally shared between two atoms. If the electronegativity of two atoms is basically the same, a nonpolar covalent bond will form, and if the electronegativity is slightly different, a polar covalent bond will form.

Answer 2

Similarities:

• They possess both a partial positive charge and which cannot cancel out.
• Electrons are involved in both kinds of bonding.

Covalent Bond:

• A covalent bond is formed when atomic orbitals from two atoms (non metals) overlap and the electrons within them form a pair that is shared by both atoms.
• The bond is held together by strong electrostatic attraction between the negative electrons and the atoms' positive nuclei.

Polar covalent bonds:

• A bond in which the electron pair is shared unequally between the two bonded atoms is called a polar covalent bond.
• Polar bonds are caused by differences in electronegativity.
• The unequal distribution of electrons causes the bonded atoms to acquire fractional positive and negative charges.

Non-polar covalent bonds:

• A bond in which the electron pair is shared equally between the two bonded atoms is called a nonpolar covalent bond.
• There is no difference in the electronegativity of the two atoms.
