Question

The electronegativity values of the elements are useful in predicting:

• A. Nature of an oxide
• B. Bond energy of a molecule
• C. All
• D. Polarity of a molecule

Answer 1

The correct option is C All

All these properties vary with the change in electronegativity.

For example, the change in values of electronegativity of the elements , bring about the change in the acidic character of oxide.

$\underset{\text{Electronegativity increases \& thus acidic character increases}}{\overset{N{a}_{2}O<B_2{O}_3<N_2{O}_5<S{O}_3<C{l}_2{O}_7}{\to }}$
