Question

Electronegativity values can be used to predict the polarity of bonds. a .Explain the term electronegativity. b. The electronegativity values for some atoms are given below: H = 2.1, F = 4.0, Cl = 3.0, Use these values to predict the polarity of each of the following bonds by copying the bonded atoms shown below and adding δ+ or δ– above each atom. i). H -F , ii). Cl -Cl​

Answer 1

Answer:

The ability of an atom to attract a pair of electrons in a chemical bond is called its electronegativity. The difference in electronegativity between two atoms determines how polar a bond will be.

Answer 2

electronegativity is the property of elements to pull the shared pair of electrons towards them in the Covalent Bonds

Hδ+ - Fδ- because electronegativity of Fluorine is more than Hydrogen
