Why was chemistry invented?
chemistry wasn't really invented. In the MIddle ages there were people called ALchemists who were looking for a way to live forever and a way to turn common metals like iron into gold. The word Chemist comes from the latin word for alchemist, alchimista. Chemists are people who study energy and matter Chemistry is the study of composition, structure, and properties of matter. Chemistry is considered to be a physical science. There are over 30 types of chemistry. It wasn't really invented, it was formed from alchemy A chemist studies the composition of matter and its small-scale properties such as density and acidity. Chemists' work deals a lot with numbers, sizes, and properties. They do this to learn the composition, structure, reactivity, and other properties of elements, mixtures, and compounds. There are over 30 types of chemistry. The work chemist comes from the Latin word chimista, an abbreviation of alchemista, which is an alchemist. An alchemist is a person who tries to change a substance to some other substance (it started out with people trying to turn common metals like iron to gold).

What is the mechanism for perkin reaction?
Start with the aromatic aldehyde and acid anhydride. Salt of an Carboxylic acid is used to abstract a proton from the alpha carbon of acid anhydride. The carbanion generated would attack the electrophillic centre of aldehyde. This centre is carbonyl carbon. There after an stablised anion is formed. Further hydrolysis gives the required Cinnamic acid.
What is the mechanism for the synthesis of E and Z alpha phenylcinnamic acid?
the perkin reaction
Is there any exceptional case of Perkin reaction?
yes synthesis of phenanthrene is an exceptional case of perkin reaction.here acetate ion is added to aromatic aldehydes though acetic anhydrides usually work it out

How will you convert benzaldehyde to cinnamic acid?
The Perkin reaction by rctn with an ethanoic anhydride and an ethanoate salt.orFirst step: Add CH2(CO2Et)2 along with Na+-OEt and ethanol to benzaldehyde. (carbonyl condensation)Second step: Add H3O+.The Perkin reaction is an organic reaction developed by William Henry Perkin that can be used to make cinnamic acids i.e. α-β-unsaturated aromatic acid by the aldol condensation of aromatic aldehydes and acid anhydrides in the presence of an alkali salt of the acid several reviews have been written. The reaction of phenylacetic acid and benzaldehyde with triethylamine and acetic anhydride to alpha-phenylcinnamic acid is an example of this reaction type.
