Explain electrometric effect. |
|
Answer» Solution :Electrometric effect : (i) The electrometric effect REFERS to the POLARITY produced in a multiple bonded compund when it is attacked by a reagent when a double or a triple bond is exposed to an attack by an electrophile the two `pi` electrons which form the `pi` bond are completely transferred to one atom or the other. (ii) When a nucleophile approaches the carbonyl compound, the `pi` electrons between C and O is instantaneously shifted to the more electronegative oxygen.This make the carbon electron deficient and thus facilitating theformation of a new bond between the incomingnucleophile and the carbonyl carbon atom.  (III) When an electrophile such as `H^(+)` approaches an ALKENE molecule the `pi` electrons are instantaneously shifted to the electrophile and a new bond is formed between carbon and hydrogen.This makesthe other carbon electron deficient and hence it acquires a POSITIVE charge.  (iv) This effect denotes as E-effect. |
