Questions and Answers

Which of the following statements is true about the sp hybrid orbital?

It is less electronegative than the sp2 hybrid orbital.

It forms shorter and stronger bonds than the sp3 hybrid orbital. (correct)

It contains more p character than the sp3 hybrid orbital.

It forms longer and weaker bonds than the sp3 hybrid orbital.

How does the change in hybridisation affect the electronegativity of carbon?

The electronegativity of carbon decreases with an increase in s character of the hybrid orbitals.

The greater the p character of the hybrid orbitals, the greater is the electronegativity.

The electronegativity of carbon is not affected by the change in hybridisation.

The greater the s character of the hybrid orbitals, the greater is the electronegativity. (correct)
