Acylation
. A base is thus added to remove the acid and facilitate the reaction. Unlike in the case of alkylation reaction, the amide formed here does not react further with the organic halide because the amide is nonbasic and a poor nucleophile due to its nitrogen unshared pair of electrons being in conjuga..

Hydrogen chloride gas can be prepared by the direct combination of hydrogen gas and chlorine gas in the presence of sunlight. The reaction is explosive in direct sunlight. However, in diffused sunlight the reaction is slow and controllable. In the dark, the reaction hardly takes place. Hy..

Acyl Halides
Acyl Halides - The most important acyl halides are acyl chlorides because they are more easily prepared, more stable and less expensi..
Alkylation and acylation
The alkylation and acylation reaction, known as 'Friedel-Craft reaction', is carried by treating haloarene with alkyl chloride or acyl chloride in the presence of a catalyst like anhydrous aluminium chloride. For example, ..

Anhydrides are on the whole less reactive than acyl chlorides..Acid Chlorides
These are derivatives of carboxylic acids in which hydroxyl (-OH) part of carboxyl group in which hydroxyl (-OH) part of carboxyl group is replaced by halo group. The most reactive compounds among acyl halides are chloro compoun..
Combination or Addition or Synthesis Reaction
Combination or Addition or Synthesis Reaction - Combination or addition or synthesis is a chemical change in which atoms or molecules of two or more substance combine to form molecules of a single new substance. For e.g., Burning of hydrogen in air or oxygen to produce water. Co..

Even though I don't feel good, the tutor helped me by totally helping me understand!
Best tutor ever. I can actually understand what to do in fraction and decimal division situations
VERY HELPFULL! I understand through the formulas given to read the equation when worked great job
Tutor are so organized and neat with their teachings. She set up everything that made the problems more understandable by showing them in such a simple manner, I feel I could really learn from them and pertain it to my class! :)
