This pairing of unpaired electron will take place by overlapping of orbitals each one having one unpaired electron with opposite spin. Which of the following combination of orbitals does not from any type of covalent bond (if z-axis is molecular axis)?

    Hybridisation is the mixing of atomic orbital of comparable energy and the number of hybrid orbitals formed is equal to the number of pure atomic orbitals mixed up and hybrid orbitals are occupied by sigma -bond pair and lone pair. ''The hybrid orbitals are at at angle of X^(@) to one another''. This statement is not valid for which of the following hybridisation?
