pls explain me the order of carbon hybridisation in accordance with electronegativity

Question

sp hybridised 'C' >sp2 hybridised 'C'>sp3 hybridised 'C'
this is the order given in accorance to electronegativity
could you explain this order

Answer 1

sp Hybridization

• This type involves mixing of one ‘s’ orbital and one ‘p’ orbital of equal energy to give a new hybrid orbital known as an sp hybridized orbital.
• The mixture of s and p orbital and the formed sp orbital is maintained at 180⁰.
• Example of sp-hybridized is: BeCl2

sp2 Hybridization

• This kind involves mixing of one ‘s’ orbital and two ‘p’ orbital’s of equal energy to give a new hybrid orbital known as sp2.
• A mixture of s and p orbital formed in trigonal symmetry and is maintained at 120⁰.
• Example of sp2 hybridized is: Ethylene (C2H4)

sp3 Hybridization

• This type involves mixing of one ‘s’ orbital and three ‘p’ orbital’s of equal energy to give a new hybrid orbital known as sp3.
• A mixture of s and p orbitals formed is in tetrahedral symmetry and is maintained at 109.28⁰.
• Example of sp3 hybridization: Ethane (C2H6)
