What is addition reaction?
What is substitution reaction?
What is flame?

Answer 1

Ans-1. In this reaction, the reagents add completely to the substrate, e.g. hydrogenation to vegetable oil to obtain ghee.

Ans-2. In this reaction, an atom or group of atoms replace another atom or group from the substrate.

Ans-3. Flame is the region where consumption of gases occur. It is of two type : blue flame (or non-luminous flame) and yellow flame (or luminous flame).

Answer 2

Explanation:

• Addition reaction:

A reaction in which one molecule combines with another to form a larger molecule with no other products.

• Substitution reaction:

Substitution reaction (also known as single displacement reaction or single substitution reaction) is a chemical reaction during which one functional group in a chemical compound is replaced by another functional group. Substitution reactions are of prime importance in organic chemistry.

• Flame:

A hot glowing body of ignited gas that is generated by something on fire.
