Concept introduction:
Acid Catalyzed Hydration Reaction: The reaction involves breaking of phi bonds between carbon-carbon multiple bonds and addition of alcohol to more substituted position of carbon in the molecule.
First step is the acid donates proton to the alkene which leads to the formation of more stable carbo cation.
Then, the water is added to the given alkene through acid catalyzed reaction where the water gets added to the carbo cation finally, the removal of one proton from oxonium ion (oxygen with one positive charge) using water results in the formation of product.
Rate determining step: In a
Activation energy: It is defined as the minimum energy required by the reacting species in order to undergo chemical reaction.
Intermediate species: It is the species formed during the middle of the chemical reaction between the reactant and the desired product.
Transition State: The state which defines the highest potential energy with respect to reaction co-ordinate between reactant and product. It is usually denoted by using the symbol ‘≠’.
Rate constant: The rate constant for a chemical reaction is the proportionality term in the chemical
