Head of Department and Teacher Interview Questions and Answers

Organic reactions involve the breaking and forming of chemical bonds in organic compounds.

• Organic reactions can be classified into different types such as addition, elimination, substitution, and rearrangement reactions.

• The mechanism of a reaction describes the step-by-step process by which the reactants are transformed into the products.

• The mechanism of a reaction can be determined by experimental evidence and theoretical calculations.

• For example, the mechanism of the SN1 re...read more

Daniel cell is an electrochemical cell that generates electrical energy from a redox reaction.

• It consists of a copper electrode immersed in a solution of copper sulfate and a zinc electrode immersed in a solution of zinc sulfate

• The two half-cells are connected by a salt bridge that allows the flow of ions

• The redox reaction occurs at the electrodes, with zinc atoms losing electrons and copper ions gaining electrons

• The flow of electrons generates an electric current that can be...read more

The MO diagram of N2 shows the bonding and antibonding orbitals of the nitrogen molecule.

• The diagram has two energy levels, one for bonding and one for antibonding orbitals.

• The bonding orbital is lower in energy and contains two electrons in a sigma bond.

• The antibonding orbital is higher in energy and is empty.

• The diagram shows that N2 has a triple bond.

• The diagram also shows that N2 is a stable molecule.
