What Is Electrophilic Addition Reaction?

Answer»

When the attacking SPECIES during the ADDITION REACTION is ELECTROPHILE, it is CALLED electrophilic addition reaction. 

Ex; (+) (­) (+) (­) (+) (­)

CH2Br­CH2BràH2C­CH2+BrBr­àH2C=CH2+Br2­

When the attacking species during the addition reaction is Electrophile, it is called electrophilic addition reaction. 

Ex; (+) (­) (+) (­) (+) (­)

CH2Br­CH2BràH2C­CH2+BrBr­àH2C=CH2+Br2­

How Do You Define Free Radical Addition Reaction?give An Example.

Answer»

When unsaturated compounds undergo ADDITION reactions with free RADICALS,it is CALLED free radical addition reaction.

Ex; CH3­CH = CH2+HBr———–> CH3­CH2­CH2Br

What Is Addition Reaction?

Answer»

When ATOMS (or) group of atoms are added, to form more saturated compound it is CALLED ADDITION REACTION.

Give The Example For Electrophilic Substitution Reaction.

Answer»

The SPECIES, which accepts the ELECTRONS, are CALLED Electrophilles (or) Electrophilic REAGENTS.

When the atom (or) group of atoms present in the organic compound is REPLACED by another atom (or) group of atoms (electrophilic) is called electrophilic substitution reaction.

The species, which accepts the electrons, are called Electrophilles (or) Electrophilic reagents.

When the atom (or) group of atoms present in the organic compound is replaced by another atom (or) group of atoms (electrophilic) is called electrophilic substitution reaction.
