Explain, how is the electronegativity of carbon atoms related to their state of hybridisation in an organic compound?

There are 3 types of hybridisation for carbon in organic compounds, sp, sp² and sp³ depending on the number of sigma and pi bonds between the carbon atoms. More the ‘s’ character more is the electronegativity of the carbon as ‘s’ orbitals are closer to the nucleus, hence electrons held more closely.
