Question

When a molecule contains a pi bond, there is a chance that the pi electrons could be spread between more than just the two atoms of the pi bond. The electrons in these molecules are said to be delocalized

Answer 1

O NO PL (5) Bonding Example : 0) chloane (1-1) only one sigma co) bond, No Di Cor) bond Glycerol only o bonds, no Pi (ht) bond 어 H 0-C 1 H H 4 서 Ć-ci ) OH H 4 1 (27 Localized pi (1) Bonding Example: Ethylene f -H 애 contain one pica bone Н H TECH HC Pi (JT) electron shared by only two carbon atom:. Localized Pi (1) Bonding ui) Acetone contein one picobond -CH3 si :: only charged separation the the between two atom :: Localized pi CTTS bond cu carbon dioxide O"co contain 2 Dj C) bond -) والا -CH3 o=c 0=CO .. only charged separation Restoicted pico electron optatim. pic eledeon ootate between two atom only .Localized pi – bonding

3) Delocalized pi CT bonding Example : û vanillin. 6 → contain 3 pi bonds 3 4 OH -OCH3 6 G 3 5 OCH3 3 -OCH 3 ои 14 4 OH Picot) electron get delocalized, foom Resonance structure. carvone JE S contain B pi bond ग T Delo coulized di CJT bond): we say that picm election droe delocalized.
Pi bonds are chemical bond which is formed by the sideway/ lateral overlap of two p orbitals

Pi bonds can form in double and triple bonds.

No pi bonding

Example : Chlorine and Glycerol

Localized pi bonding

Localized chemical bonding defined as bonding in which the the electron are shared by two and only two atom.

Example: Ethylene, Acetone,Carbon dioxide

Delocalized pi bonding

Delocalized chemical bonding in which compound electron are shared by more than two atom

Example:Vanillin, Carvone
