Solution

The correct option is C $+ E$ effect

If the attacking species is an electrophile, the electrons are transferred towards the positively charged atom. This is known as: $+ E$ effect.Follow the given example.
Hence option C is correct.

Q. If the attacking reagent is a nucleophile, the electrons are transferred away from the attacking reagent and into the system. This is known as:

Q. i) Involves complete shifting of

electrons.
ii) It is a temporary effect.
iii) In -E effect ,

π

electrons of the multiple bond are transferred to the atom to which the reagent gets attached.
iv) It operates in organic compounds having multiple bonds under the influence of an outside attacking species.
How many statements are correct regarding Electromeric effect from above.

Q. Alkenes and alkynes both undergo electrophilic addition because of

π

electron density, they behave as electron rich species. Alkenes are more reactive towards this reaction because the intermediate formed when an electrophile adds to an alkyne is a vinylic cation whereas the intermediate formed when an electrophile adds to alkene is alkyl cation, which is more stable.

Q. Electron deficient species are called electrophiles and they are only positively charged.

A carbocation is a group of atoms with a positively charged carbon atom having six electrons in the valence shell after sharing. Carbocations are formed in the heterolysis of a bond and are planar species. Stability of carbocation is determined by inductive effect, hyperconjugation and resonance effect. Greater the number of contributing structures more is the stability of a Carbocation. Electron releasing groups (+I effect) increases the stability of a carbocation whereas the electron withdrawing groups (I effect) have an opposite effect.

Which of the following is most stable carbocation?
