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..

A large number of chemical reactions will be taking place in a cell. The rate and efficiency with which these reactions go on in a cell, depend on a group of macromolecules called enzymes. Enzymes are thus, biological catalysts. Enzymes are synthesised by li..
Enzymes
Enzymes are the biocatalysts of life. They are defined as biocatalysts synthesized by living cells. They are simple or conjugate protein and specific in action. At present about 300 enzymes are recognized and classified into six classes by International Union of Biochemistry (IU..
Classification of Enzymes
Classification of Enzymes - Enzymes are generally classified on the basis of the type of reactions that they catalyse. 6 groups of enzymes can be recognised on this basis. The following table lists the 6 groups of enzymes along with exampl..

>o C. Enzyme activity decreases below and above this range of temperature. Each enzyme requires a specific pH for its activity. Enzyme activity decrease below and above this optimum pH. Enzymes generally work in groups in a cell. The product one ..
Enzyme Catalysis
The remarkable specificity of enzymes comes from the ability of the enzymes to bring the substrates into a favorable orientation in the enzyme-substrate (ES) complexes such that the substrates are bound to specific regions of the enzymes. Each enzyme..
Nomenclature of Acyl Halides
Nomenclature of Acyl Halides - Acyl halides (sometimes also called acid halides) are named by identifying the acyl group (RCO) and then the halide. The name of the acyl group is derived from the name of the corresponding -ic acid by replac..

Tertiary amines do not react with acyl chlorides. iii) Acyl chlorides react with alcohols and phenols to give esters. The cleavage of a bond with alcohol is called alcoholysis. In these reactions, an acyl group is transferred to the nucleophiles. These reacti..
Functional Groups in Carboxylic Acid Derivatives
Structures of Functional Groups Present in Carboxylic Acid Derivatives - The structure of the functional groups in acyl halide, acid anhydride, ester and amide are similar to that of the carboxyl group. Due to the presence of lone pairs of electrons at the ha..

The structure of the functional groups in acyl halide, acid anhydride, ester and amide are similar to that of the carboxyl group. Due to the presence of lone pairs of electrons at the halogen, oxygen and nitrogen atoms, resonance is possible in these derivatives ..

Tutors are very patient to explain me the same problem again and again until i understand...Really helpful...Thank you all...
I am Jessica from New York, I got excellent English tutors from Tutor Vista, who helped me lot to overcome my grammar mistakes, Thanks a lot...
We have a single tutor for 40 students in school, where as I have a personal tutor for myself with Tutor Vista, It's a great help -Joe
For every concept, here we get explanation along diagrams, I really liked it very much
