Which of the following molecules represents the order of hybridisation sp2, sp2, sp, sp from left to right atoms ?

  • Option 1)

    CH2 = CH — CH = CH2

  • Option 2)

    CH2 = CH — C\equivCH

  • Option 3)

    CH\equivalent\equivC-C \equivCH

  • Option 4)

    CH3 — CH = CH — CH3

As we learnt that

Hybridisation -

The process of mixing of atomic orbitals belonging to the same atoms of slightly different energies so that a redistribution of energy takes place between them  resulting in the formation of new set of orbital of equivalent energies and shape is called hybridisation.

- wherein

The new orbitals thus formed are called hybrid orbitals

 

 CH_{2}=CH-C\equiv CH

   sp2            sp2     sp          sp

 


Option 1)

CH2 = CH — CH = CH2

This is incorrect.

Option 2)

CH2 = CH — C\equivCH

This is correct.

Option 3)

CH\equivalent\equivC-C \equivCH

This is incorrect.

Option 4)

CH3 — CH = CH — CH3

This is incorrect.
