Explain why alkyl groups act as electron donors when attached to a n system

Text Solution

Verified by Experts

Due to hyperconjugation, alkyl groups act as electron donors when attached to a `pi` system. For example, let us consider hyperconjugation in propene.

Explain why alkyl groups act as electron donors when attacted to a pi-system .

Explain why can more than 8 electrons not be accommodated in L shell?

The resonance effect is defined as 'the polarity produced in the molecule by the interaction of two pi -bonds or between a pi -bond and lone pair of electrons present on an adjacentatom.' The effect is transmitted through the chain. In positive resonance effect, the transfer of electrons is away from an atom or substituent group attached to the conjugated system. This electron displacement makes certain positions in the molecule of high electron densities. In negative resonance effect, the transfer of electrons is towards the atom or substituent group attached to the conjugated system. Which of the following does not show resonance effect ?
