How does a bond become polar?

Usually it just is polar. It happens when one of the atoms has a greater electronegativity (attraction for electrons) than the other, so more of the electron density is at that end of the bond.

How can you tell if a bond bond is polar or non-polar?

Check the electronegativities of the atoms in the bond. The bond will be polar if there is a difference in electronegativity. The most electronegative element will attract the bonding eletrons to it becoming slightly negatively charged. The other end of the bond will become slightly positively charged. For example a bond between carbon and chlorine, C-Cl: C electronegativity 2.55 Cl electronegativity 3.16 The bond will be polar because of the difference in electronegativity, and Cl will be slightly negative, carbon slightly positive.

Does HF have a polar covalent bond?

yes it is a polar covalent bond. the difference of electronegativities of H and F is 1.9 , it should be an ionic bond but the ratio of atomic sizes of both the atoms is responsible for polar covalent bond.


If atoms that share electrons have an unequal attraction for the electrons the bond is called?

If atoms that share electrons have an unequal attraction for the electrons, the bond is called a polar covalent bond. This occurs when one atom has a higher electronegativity than the other, leading to an uneven distribution of electrons in the bond.


What causes a covalent bond to become polar?

A covalent bond becomes polar when the two atoms involved in the bond have different electronegativities, causing unequal sharing of electrons. This leads to a partial positive charge on one atom and a partial negative charge on the other, creating a dipole moment in the bond.

Polar covalent. The difference in electronegtivity is insufficient for an ionic bond
