Question

Electronegativity describes the ability of an atom to attract additional electron density to itself. Electronegativity would help predicting all of the following except.
Select one: a. Solubility of a substance in water. b. The amount of energy needed to ionize a sample of gas. c. The amount of energy needed to remove an electron from the outer orbital of a noble gas. d. The expected size of a crystal of naphthalene when it deposits as crysts.

Explanation / Answer

the correct option is (d)

solubility of a substance can be determined by electronegative difference between atoms. If the difference in electronegativity of the atoms is more the compound is polar and disolve in water.

If the atom has high electronagativity, the amount of energy required to remove lectron ( ionise) is more.

In case of noble metals also, the increase in electronegativity more energy is needed to remove an electron.

the option (d) is not relavent to electronegativity here.
