Four atoms are arbitrarily labeled D, E, F, and G. Their electronegativities are as follows: D = 3.8, E = 3.3, F = 2.8, and G = 1.3. If the atoms of these elements form the molecules DE, DG, EG, and DF, how would you arrange these molecules in order of increasing covalent bond character?

    Answer: DG < EG< DF< DE

    Explanation:

    Electronegativity is defined as the property of an element to attract a shared pair of electron towards itself.

    Lower is the electronegativity diffrence, more will be the covalent character. Higher is the electronegativity diffrence, more will be the ionic character.

    1. DE: Electronegativity difference = electronegativity of D - electronegativity of E = 3.8-3.3 = 0.5

    2. DG: Electronegativity difference = electronegativity of D - electronegativity of G = 3.8-1.3 = 2.5

    3. EG: Electronegativity difference = electronegativity of E - electronegativity of G = 3.3-1.3 = 2.0

    4. DF: Electronegativity difference = electronegativity of D - electronegativity of F = 3.8-2.8 = 1.0

    Thus the order of increasing covalent character is DG < EG< DF< DE
