1. Define Solvent, Solute, Solution.

  • Solution: - A solution in chemistry is a homogeneous mixture of two or more substances.
  • Solute: - A substance which is dissolved in solvent is called solute.
  • Solvent: - The substance in which the solute is dissolved is called a solvent.
Solvent, Solute, Solution.

2. What is buffer Solution?

A Solution that resistance towards change in pH of solution basicity it is either made of a weak acid and a conjugate base or a weak base and a conjugate acid.

3. When the volatility difference between two components is very less which types distillation use? Why?

Extractive distillation or azeotropic distillation is used depending upon nature of the liquid mixture.

4. Define: - Electronegativity and Bond.

Electronegativity: - Tendency of any atom to attract bonding electron towards itself.
Bond: - The linkage between atom in molecules.

5. Define 𝝈 and 𝝅 bond

𝝈 bond: - This type of co valent bond formed by the end to end overlap of bonding orbital. Along the inter nuclear axis. this is called as head on overlap axial.
𝝅 bond: - In the formation of 𝜋 bond the atomic orbital overlap in such  a way that  their axes remain parallel to each other end perpendicular to the inter nuclear axis.
Butanol  have  14 𝝈 bond, no  𝜋 bond

6. Define atomic no and atomic Weight.

  • Atomic (Z): -The no. of protons in the nucleus of atom is called Atomic no.
  • Atomic Weight: - the sum of protons and neutrons in the nucleus of atom is called atomic

7. Give full form of COD, BOD, TDS, PPM, CGMP & GMP. COD-Chemical Oxygen Demand

The amount of oxygen present in water consume during two hrs by the organic and inorganic contaminant
  • BOD-Biological Oxygen Demand
BOD is the amount of dissolve oxygen needed by biological organism to break down organic material present in one liter water during five days at 20 degree Celsius.
  • TDS- Total dissolved solid
  • PPM- Parts per million
  • CGMP-Current good manufacturing practice.
  • GMP-Good manufacturing practice.
  • GLP-Good laboratory Practice.

8. Define Fire Point and Flash Point. What is the importance of determination of Fire Point?

·         Flash Point: - It is the lowest temperature at which vapour of fluid will produce a flash by open flame.

·         Fire Point: -It is the lowest temperature  at which  the  vapour  of fluid  will  continue  to burn for at least 5 seconds after ignition by open flame.

9. Define: - Isomer, Iso
