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..

Acid chlorides contain the functional group -COCl. This functional group is obtained by replacing the -OH group of a carboxyl group with a chlorine atom. The common name of an acid chloride is obtained by replacing the ending -ic acid from the common name of the parent aci..
Reaction of acyl halides
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 ..
With Alcohols

General Methods of Preparation from Alcohol and Acid Chlorides
Aldehydes and ketones are generally prepared by oxidation of primary and secondary alcohols respectively. Common oxidising agents are KMnO 4 , K 2 Cr 2 O 7 and CrO 3 . Strong oxidising agents oxidise the aldehyde produced by the oxidation of a primary alcohol to carboxyli..
Acid 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..

By the dehydration of alcohols
Alkenes are obtained by the dehydration of alcohols. The dehydration of alcohols can be affected by two common methods. By passing the vapors of an alcohol over heated alumina. By heating an alcohol with concentrated mineral acid, such as concentrated H..
