Option (iii) is the correct answer.
Electronegativity of carbon atoms depends upon their state of hybridisation. In which of the following compounds, the carbon marked with an asterisk is most electronegative? (i) CH3 – CH2 – *CH2 –CH3 (ii) CH3 – *CH = CH – CH3 (iii) CH3 – CH2 – C ≡ *CH (iv) CH3 – CH2 – CH = *CH2
