What Are Acid Chlorides

STEP 2 Reaction of a nucleophile and an electrophile to form a new covalent bond. The 

STEP 3 Take a proton away. Proton transfer from the oxonium ion to a second molecule of alcohol gives a tetrahedral carbonyl addition intermediate (TCAI)  

STEP 4 Add a proton. Proton transfer to one of the —OH groups of theTCAl gives a new 

STEP 5 Collapse of the tetrahedral carbonyl addition intermediate to eject a leaving group and regenerate the carbonyl group. Loss of water from this oxonium ion gives the ester and regenerates the acid catalyst  

The functional group of an acid halide is a carbonyl group bonded to a halogen atom. Among the acid halides, acid chlorides are the most frequently used in the laboratory and in industrial organic chemistry
