Q5P - Chemistry: Molecular Nature Of Matter And Change

Question

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

(a) two d, one s, and one p

(b) three p and one s

Step-by-Step Solution

Answer

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

Step1:For two d, one s,and three p

Whentwo d, one s, and three porbitals were mixed  ${\mathbf{d}}^{\mathbf{2}}{\mathbf{sp}}^{\mathbf{3}}$hybrid orbital formed.Its geometryis anoctahedral arrangement of six hybrid orbitals.

Step2: For three pand one s

Whenthree p and one swere mixed ${\mathbf{sp}}^{\mathbf{3}}$ hybrid orbital formed.Its geometry is a tetrahedralarrangement of four hybrid orbitals.
