Question

Why it is not easy to remove a hydrogen from sp2 carbon atom??

Answer 1

Answer:

electrons are closer to the nuclei than the p electrons (while in same energy level), so the bonds made up of s electrons are shorter than those made up of p electrons, extrapolate from this, the more s componet in the spx hybrid orbital, the shorter the bond. a shorter bond often means a stronger bond

SECOND ANSWER

A bond between sp3 and sp2 is stronger than a bond between sp3 and sp3 because sp2 hybridized orbitals contains 33.33% s-character while sp3 contains 25% s-character. A general rule, the more s-character in a hybridized orbital, the stronger a bond it will form. Thus a bond between sp3 and sp2 with 33.33% + 25% % s-character will be more strong than a bond between sp3 and sp3 with 25% + 25% s-character.
