Question

During sp hybridization, a total of _____ new hybrid orbitals are formed. These hybrid orbitals have a bond angle of ______.

• A. five, ${180}^o$
• B. two, ${180}^o$
• C. four, ${109.5}^o$
• D. three, ${120}^o$

Answer 1

The correct option is B two, ${180}^o$

$\bullet$ Hybridisation is a process in which two or more orbitals of comparable energy intermix to form same number of hybrid orbitals having equal energies and same shape.

$\bullet$ $\text{sp}$ hybridisation is observed when one s and one p orbitals intermix to form three orbitals having identical energy and shape.

$\bullet$ The sp hybrid orbitals form molecules with linear geometry, with a bond angle of ${180}^o$ to minimise the electronic repulsion.
