Q29 of 66 Page 149

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.
