Question

Tendency of one atom to attract the lectron of a bond pair towards itself is known as electronegativity. Orbital which contain more $\%$ of $S$ character, the associated atom with that orbital has more electron negativity. Which of the following statement is correct?

• A. bond order increases when $\%$ of $p$ character in hybrid orbital of $C$ increases
• B. in above examples order of $d_{C-C}$ bond length $I>II>III$.
• C. when $E.N$ increases reactivity not change
• D. when difference of $EN$ increases, $\%$ of ionic character in a bond increases

Answer 1

The correct option is D when difference of $EN$ increases, $\%$ of ionic character in a bond increases

When a difference of electronegativity increases, the percentage of ionic character in bond increases as the electrons are more strongly attracted by more electronegative atom.
