Questions and Answers

What is the term used to describe the delocalisation of electrons of a bond?

Electromeric effect

Inductive effect

Resonance

Hyperconjugation (correct)

What type of orbitals do the electrons of a σ-bond typically interact with in hyperconjugation?

Anti-bonding π-orbital

Filled s-orbital

Empty non-bonding p-orbital or anti-bonding σ* or π*-orbitals (correct)

Filled non-bonding p-orbital

How does hyperconjugation differ from the electromeric effect?

Hyperconjugation occurs in alkanes, while the electromeric effect occurs in alkenes

Electromeric effect involves π-bonds, while hyperconjugation involves σ-bonds

Hyperconjugation is a permanent effect, while the electromeric effect is temporary (correct)

Electromeric effect results in the formation of a new compound, while hyperconjugation does not

Study Notes

Bonding and Electron Delocalization

The term used to describe the delocalization of electrons of a bond is resonance.

Hyperconjugation

In hyperconjugation, the electrons of a σ-bond typically interact with adjacent parallel p-orbitals.
Hyperconjugation differs from the electromeric effect in that it involves the delocalization of electrons in a σ-bond, whereas the electromeric effect involves the delocalization of electrons in a π-bond.
