Hybridization and Bond Strength: Arranging sp³, sp², and sp¹ Orbitals

Understanding Hybridization and Bond Strength

Hybridization is the process where atomic orbitals mix to form new hybrid orbitals of equal energy, helping in bond formation and molecular stability. The type of hybridization directly influences bond strength, bond length, and molecular geometry.

 Bond Strength and Hybridization

The strength of a bond depends on the percentage of s-character in the hybrid orbital:

• sp hybridization → 50% s-character → strongest bond
• sp² hybridization → 33.3% s-character → moderate strength
• sp³ hybridization → 25% s-character → weakest bond

Since s-orbitals are closer to the nucleus, a higher s-character means greater bond strength and shorter bond length.

 Arranging sp³, sp², and sp¹ in Decreasing Order of Strength

The correct order of bond strength is:

sp > sp² > sp³

Thus, the correct answer is:

Option (2) sp¹ > sp² > sp³

Real-World Examples of Hybridization and Bond Strength

• sp Hybridization: Found in alkynes (C≡C), where the bond is the shortest and strongest.
• sp² Hybridization: Present in alkenes (C=C), with moderate bond strength.
• sp³ Hybridization: Found in alkanes (C-C), where bonds are the longest and weakest.
