define the types of hyperconjugation ??
Answers
Explanation:
Hyperconjugation is described as the stabilizing interaction, results from the interaction of the electron in a σ-bond (in general, C-C or C-H) with either an adjacent partially filled or empty p-orbital or a π-orbital to form an extended molecular orbital, which increases the stability of the system.
Answer:
The displacement of an electron in an organic molecule can take place because of the presence of an appropriate attacking reagent. Such kind of electron displacement leads to bond polarization. A few effects that feature this electron displacement can be given as hyperconjugation and electromeric effect, where a brief explanation is provided below:
Electromeric Effect and its Types:
The electromeric effect is a temporary effect, which is experienced primarily in the presence of a vicinity's attacking reagent of an organic compound containing the multiple bonds (either a double or triple bond). In this effect, the complete transfer of the mutual pair of π-electrons to one of the atoms, along with several bonds, occurs at the request of the attacking reagent. Also, this effect ceases soon as the attacking reagent is removed from the reaction's domain. The electromeric effect is primarily categorized into 2 categories, which are listed below.
Positive Electromeric Effect (The +E Effect):
The positive electromeric effect can be described as the transfer of the π−electrons of the multiple bonds to the atom, where the reagent gets attached.

Negative Electromeric Effect (The –E Effect):
The positive electromeric effect can be defined as the transfer of several bonds to the atom, where the reagent is not attached.

Mesomeric Effect
The mesomeric effect is described as a property of substituents or functional groups, that are present in a chemical compound.
The mesomeric effect or Negative resonance can be denoted by -M or -R.
