Competition Science Vision
Thus, the complete transfer of shared pair of re electrons of a multiple bond to the
more electronegative atom of bonded atoms due to requirement of attacking
reagent is known as electromeric effect (E effect). When the transfer of electrons ...

p: (-E effect) Nucleophile Substrate CN Nucleophilic addition The addition of
polar reagent on C=C or C=O bonds proceeds due to polarisation of these bonds
as a result of electromeric effect. Thus addition reactions of alkenes and
aldehydes ...
3.2.2 Electromeric Effect It is a temporary effect which comes into play with the
approach of attacking reagent. When a double or a triple bond is attacked by an
electrophilic reagent, a pair of bonding electrons is completely transferred from
one ...

THE INDUCTOMERIC AND ELECTROMERIC EFFECTS Physical methods such
as the measurement of acid and base strengths, the measurement of dipole
moments, and the determination of the lengths of C — X bonds, etc., all give an ...

Electromeric Effect • This is a temporary effect operating in unsaturated
compounds only at the demand of another reagent. It involves the complete
transfer of n electrons of a multiple bond. It is represented by 'E'. • During the
attack of a ...
+ or H2C=CH2 > H2C— CH2 On the other hand, if the multiple bond is present
between two different atoms, then the direction of electromeric shift is determined
by the direction of the inductive influence of the group present on the doubly (or ...
Reagent \ + yC— O [C] fD] Electromeric effect in carbonyl compounds Alkenes, as
such, exist as non-polar species but in presence of a reagent, the ^-electrons shift
towards one of the carbon and the system behaves as a highly polar single ...

A Textbook Of Organic Chemistry, 3E
Usually the electromeric effect precedes a polar or ionic addition reaction. In
cases, where the constituent atoms linked by the multiple bond are similar, the
direction of electromeric shift is not important. As displacement of electrons to
either of ...

Electronics Engineering
The attacking reagent forms a bond with the positively charged carbon. It is
obvious that the electron pair cannot be transferred to carbon in view of the
greater electronegativity of oxygen. The electromeric effect is denoted by the
symbol E. The ...

Textbook of Environmental Chemistry
Electromeric effect (E-effect) involves complete transfer of electrons of a multiple
bond to more electronegative atom of the π bond in the presence of an attacking
reagent. It is a temporary effect and brought into play instaneously at the demand
