Most Important Reagents

Reagents:-

                 A substance use in the chemical Reaction whose started or end the the rate of chemical reaction.

 Type of Reagents:-

                                      Especially two types of Reagents

A) Electrophile (+)

B) Nucleophile (-)

A) Electrophile:-

                             Electrophile have positive charge and accept election into empty low - energy orbitals represent by one of the following.

1. A positive charge representing an empty orbitals. Like (H+)

2. A neutral molecule with an empty p orbitals. Like (BF3)

3. A double bond to an electronegative element. Like ( CH3-CO-CH3)

4. A single bond to an electronegative element. Like ( HCl ) 

B) Nucleophile:-

                              It have negative charge and denotes election from high - energy orbitals represent by one of the following. 

A) A lone pair. Like ( NH3)

B) A negative charge. Like ( Br-)

C) have a double bond. Like ( CH3 - CH3)

D) A Sigma bond to an electronegative element. Like ( Li-CH3)
