Hybridisation - Types of Hybridisation

Distinguish between a sigma and a pi bond.

What do you understand by bond pairs and lone pairs of electrons? Illustrate by giving one example of each type.

Apart from tetrahedral geometry, another possible geometry for CH₄ is square planar with the four H atoms at the corners of the square and the C atom at its centre. Explain why CH₄ is not square planar?

Draw a diagram showing the formation of a double bond and a triple bond between carbon atoms in C₂H₄ and C₂H₂ molecules.

What is the total number of sigma and pi bonds in the following molecules?

C₂H₄

What is the total number of sigma and pi bonds in the following molecules?

Isostructural species are those which have the same shape and hybridisation. Among the given species identify the isostructural pairs.
