Question

Give the number and type of hybrid orbital that forms when each set of atomic orbitals mixes:

(a) one p and one s

(b) three p, one d, and one s

Short answer

The new orbitals formed by intermixing of atomic orbitals arecalled hybridization and new orbitals formed are called hybrid orbitals.Its number depends upon the total number of atomic orbitals mixed.

Step-by-step solution

Step1:For one p and one s

When one s andone porbitals were mixed sp hybrid orbital formed.Its geometry is a linear arrangement oftwo hybrid orbitals.

Step2:For three p, one d, and one s

When one s, three p and one d were mixed ${\mathbf{sp}}^{\mathbf{3}}$ hybrid orbital formed.Its geometry is a trigonal bipyramidal arrangement offive hybrid orbitals.
