Types of reaction
Chemical reactions can be classified into several types based on the nature of reactants and products
Some common types of reactions include synthesis, decomposition, combustion, displacement, and redox reactions
Synthesis reactions combine two or more substances to form a new compound, e.g., A + B → AB
Decomposition reactions break down a compound into its constituent elements or simpler compounds, e.g.,...

I applied via Referral and was interviewed before Sep 2020. There was 1 interview round.
The interview question covers topics such as Lewis acid, pH, acid and base, organic chemistry, periodic table, chemical formulas, and pH measurement without a pH meter.
Lewis acid is an electron acceptor, examples include AlCl3 and FeCl3
pH is a measure of acidity or basicity, with a range of 0-14
Acids donate H+ ions, bases accept H+ ions
Organic chemistry deals with carbon-based compounds, examples include ethanol and gl...
Benzene is a colorless, highly flammable liquid with a sweet odor. It is a basic building block of many chemicals.
Benzene is a hydrocarbon with the chemical formula C6H6.
It is a natural constituent of crude oil and gasoline.
Benzene is used in the production of plastics, synthetic fibers, rubber, dyes, detergents, and pharmaceuticals.
Exposure to benzene can cause cancer and other health problems.
Benzene is also a major ...
Water has a boiling point of 100°C and a melting point of 0°C. Other solvents have varying boiling and melting points.
Water has a high boiling point due to its strong hydrogen bonding
Solvents like ethanol have lower boiling points than water
Melting points of solvents depend on their molecular structure
Some solvents like mercury are liquid at room temperature
Boiling and melting points are important in chemical reactions

The Grignard reaction involves the addition of an organomagnesium halide to a carbonyl group.
The reaction is named after French chemist Victor Grignard.
It is used to form carbon-carbon bonds and is a key reaction in organic synthesis.
An example is the synthesis of triphenylmethanol from benzophenone and phenylmagnesium bromide.
The reaction proceeds through the formation of a Grignard reagent, which then attacks the car...
Titration is a technique to determine the concentration of a substance in a solution. pH is a measure of acidity or basicity of a solution.
Titration involves adding a solution of known concentration to a solution of unknown concentration until the reaction is complete.
pH is measured on a scale of 0-14, with 7 being neutral, below 7 acidic, and above 7 basic.
Titration can be used to determine the concentration of acids,...
