Question

Bond energy is highest in the overlapping 1) sp2-s 2) sp2- s
3)sp-s
4)sp3-s

Answer 1

Answer:

Option 3 is correct sp-s

Answer 2

(c) sp-s has the highest bond energy of overlapping.

Explanation:

• s orbitals hold electrons more tightly to the nucleus than p orbitals.
• The greater the s character, the closer are the electrons to the nucleus.
• The greater the s character, the shorter and stronger is the bond.
• Shorter and stronger bonds signify more overlapping between orbitals.
• Due to all these reasons, bond length in sp³ hybridized atoms is greater than sp² and sp hybridized atoms, and bond strength in sp³ hybridized atoms is less than sp² and sp hybridized atoms.
