Chemical Catalysis

Question 1

What is homolytic fission

Answer 1

Homolytic fission is a chemical bond dissociation of a molecule by a process where each of the fragments retain one of the originally bonded electrons equally

Question 2

What is heterolytic fission

Answer 2

It involves cleavage of a chemical bond in a process where both of the electrons involved in the original bond remains with only one of the fragment species

Question 3

What are all the 4 types of reactions organic compounds participate in

Answer 3

1) Substitution reaction
2) Addition reaction
3) Elimination reaction
4) Rearrangement reaction

Question 4

What is acid base catalysis

Answer 4

Acid base catalysis is the acceleration of a chemical reaction by the addition of the acid or a base without the acid or base itself being consumed
Ex : Decomposition of sugar, sulfuric acid is used
Addition of hydrogen cyanide to aldehydes and ketones in the presence of sodium hydroxide

Question 5

What is electrostatic catalysis

Answer 5

A transition state may be stabilized by electrostatic interaction between it’s charged groups and charged groups acts as a catalyst
Ex hydrolysis of glycine esters
