Solution
The correct option is A
Hybridisation of ‘C′ in organic compounds
● Electronegativity of carbon depends upon the state of hybridisation.
● As the percentage of s-character in the hybridisation of carbon atoms increases, the electronegativity increases.
● sp Hybridised carbon is most electronegative. It has 50% s-character.
So, the carbon marked with asterisk of compound (C) is sp hybridised. Thus, this carbon is most electronegative among the given compounds with 50% s−character.
Hence, the correct choice is Option (C).
