Cipla QA QC Chemist Interview Questions, Process, and Tips

Chemistry is branch of study the all organic and inorganic chemicals and components

Synthesis of a chemical reaction involves combining reactants to form products through a series of steps.

• Identify reactants and products

• Determine the stoichiometry of the reaction

• Select appropriate reaction conditions (temperature, pressure, catalyst)

• Follow reaction mechanism to understand the steps involved

• Purify and isolate the final product

The elements in 1 to 10 are Hydrogen, Helium, Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, Neon.

• Hydrogen

All type of protein and vitamin and synthesis of all components

Ammonia reacts with acids to form ammonium salts, with metals to form amides, and with halogens to form salts.

• Ammonia reacts with acids to form ammonium salts (e.g. NH3 + HCl -> NH4Cl)

• Ammonia reacts with metals to form amides (e.g. 2NH3 + 2Na -> 2NaNH2 + H2)

• Ammonia reacts with halogens to form salts (e.g. NH3 + HCl -> NH4Cl)

Chemical names are unique identifiers for specific substances used in chemistry.

• Chemical names can be systematic (following specific rules) or common (based on historical usage)

• Examples of chemical names include: sodium chloride, hydrogen peroxide, sulfuric acid

Organic chemistry is the branch of chemistry that deals with the study of carbon-containing compounds.

• Focuses on the structure, properties, composition, reactions, and synthesis of carbon-based compounds

• Includes the study of hydrocarbons, alcohols, acids, esters, and more

• Important in pharmaceuticals, petrochemicals, plastics, and other industries

Inorganic chemistry is the branch of chemistry that deals with the study of inorganic compounds, which do not contain carbon-hydrogen bonds.

• Focuses on elements other than carbon

• Studies properties and behavior of inorganic compounds

• Includes metals, minerals, and non-carbon containing compounds

• Examines reactions and synthesis of inorganic substances

Acids react with bases to form salts and water.

• Acids react with bases to form salts and water

• Acids can also react with metals to form hydrogen gas and a salt

• Strong acids like hydrochloric acid can react with carbonates to form carbon dioxide gas, water, and a salt
