Gland Pharma Interview Questions, Process, and Tips

Q1. Define molarity
Ans. 
Molarity is a measure of concentration, defined as moles of solute per liter of solution.
• Molarity (M) = moles of solute / liters of solution.

• Example: 1 M NaCl solution contains 1 mole of NaCl in 1 liter of water.

• Used in chemistry to prepare solutions with precise concentrations.

• Important for stoichiometric calculations in reactions.

Q5. Define Normality
Ans. 
Normality is a measure of concentration equivalent to the number of equivalents of solute per liter of solution.
• Normality (N) is defined as the number of equivalents of solute per liter of solution.

• It is commonly used in acid-base reactions, where 1 N solution of HCl can donate 1 equivalent of H+ ions.

• For example, a 1 N solution of sulfuric acid (H2SO4) provides 2 equivalents of H+ ions per mole.

• Normality is particular...read more

Q6. Molecular weight of oxygen
Ans. 
The molecular weight of oxygen (O2) is approximately 32 g/mol, calculated from its atomic mass.
• Oxygen exists primarily as O2, a diatomic molecule.

• The atomic mass of a single oxygen atom is about 16 g/mol.

• Thus, for O2: 16 g/mol (O) x 2 = 32 g/mol.

• Molecular weight is crucial in stoichiometry for chemical reactions.

Q7. Write any one named reaction
Ans. 
The Diels-Alder reaction is a cycloaddition between a diene and a dienophile to form a six-membered ring.
• Involves a diene (e.g., 1,3-butadiene) and a dienophile (e.g., maleic anhydride).

• Forms a cyclohexene derivative as the product.

• It is a [4+2] cycloaddition reaction.

• Used in the synthesis of complex organic molecules.

• Example: The reaction of 1,3-butadiene with maleic anhydride yields cyclohexene derivatives.

Q1. Define the principle of tlc
Ans. 
TLC stands for Thin Layer Chromatography, a technique used to separate and analyze mixtures of chemicals.
• TLC involves a stationary phase (thin layer of adsorbent material) and a mobile phase (solvent).

• The sample mixture is spotted on the TLC plate and the plate is placed in a developing chamber with the mobile phase.

• Different components of the mixture move at different rates on the plate, allowing for separation and id...read more

Q2. Disintegration and dissolution difference
Ans. 
Disintegration is the breakdown of a solid dosage form into smaller particles, while dissolution is the process by which a solid substance dissolves in a liquid.
• Disintegration is a physical process, while dissolution is a chemical process.

• Disintegration involves the breaking down of a tablet or capsule into smaller pieces, while dissolution involves the solubilization of the active ingredient.

• Disintegration testing is ...read more
