Question

which of the following statement is true about polar bonds

(a) they are present in metals

(b) they are responsible for formation of ionic compounds

(c) they always result to the formation of polar molecular compounds

(d) they may result to non polar covalent compounds depending on molecular geometry ​

Answer 1

Answer:

Polar Bond Definition

A polar bond is a covalent bond between two atoms where the electrons forming the bond are unequally distributed. This causes the molecule to have a slight electrical dipole moment where one end is slightly positive and the other is slightly negative. The charge of the electric dipoles is less than a full unit charge, so they are considered partial charges and denoted by delta plus (δ+) and delta minus (δ-). Because positive and negative charges are separated in the bond, molecules with polar covalent bonds interact with dipoles in other molecules.

Answer 2

Answer:

They may result to non polar covalent compounds depending on molecular geometry.

Explanation:

• A polar bond is a covalent link formed by two atoms in which the distribution of the bond's electrons is uneven. One end of the molecule becomes slightly positive and the other slightly negative as a result, creating a little electrical dipole moment. The electric dipoles have partial charges that are represented by the symbols delta plus (+) and delta negative (-) since their charge is less than a full unit charge.
• Pure covalent bonding and pure ionic bonding are separated by polar bonds. Atoms in pure covalent bonds (also known as nonpolar covalent bonds) share identical electron pairs.
• According to science, nonpolar bonds can only form when two atoms are similar to one another (e.g., H2 gas).
