Biochemistry Interview Questions and Answers will guide you that Bio Chemistry is the study of the chemical processes in living organisms. It deals with the structure and function of cellular components such as proteins, carbohydrates, lipids, nucleic acids and other biomolecules. Among the vast number of different biomolecules, many are complex and large molecules (called polymers), which are composed of similar repeating subunits, Learn Biochemistry Interview Questions with Answers Guide

2 :: What is electrophilic addition reaction?

When the attacking species during the addition reaction is Electrophile, it is called electrophilic addition reaction. Ex; (+) (-) (+) (-) (+) (-)
CH2Br-CH2BràH2C-CH2+BrBr-àH2C=CH2+Br2-

4 :: How do you define free radical addition reaction? Give an example.

When unsaturated compounds undergo addition reactions with free radicals,
it is called free radical addition reaction.
Ex; CH3-CH = CH2+HBr-----------> CH3-CH2-CH2Br

6 :: Give the example for electrophilic substitution reaction.

The species, which accepts the electrons, are called Electrophilles (or) Electrophilic reagents.

When the atom (or) group of atoms present in the organic compound is replaced by another atom (or) group of atoms (electrophilic) is called electrophilic substitution reaction.

7 :: What are the favorable conditions for formation of Anions?

► High Electron affinity
► Small size

Less charge of an atoms form anion more easily

8 :: Define lattice energy.

The energy released when one mole of ionic crystal is formed by the combination of the corresponding gaseous (+ve) and (-ve) ions brought from infinite distance is called lattice energy.
Post Your Answer

9 :: What happens if Lattice energy increases?

► The Strength of ionic bond
► Stability of the Ionic compound
► Ease of formation of the Ionic bond Increases
Post Your Answer

10 :: What is Sublimation energy?
