Hybridisation of carbon = sp3-number of π-bonds In CO2 , 1π 1π(O = C = O) hybridisation of carbon =sp3-2=sp In ethyne or acetylene , C2H2 , (H - C ≡2π C - H) hybridisation of carbon = sp3-2=sp

Q. Which of the following organic compounds has same hybridisation as its combustion (CO $_{2}$ ) product?

Ethane

Ethyne

Ethene

Ethanol

Hybridisation of carbon = $s p^{3 - n u mb er o f π - b o n d s}$
In $C O_{2},$ $_{1 π 1 π}^{(O = C = O)}$ hybridisation of carbon
$= s p^{3 - 2} = s p$
In ethyne or acetylene , $C_{2} H_{2}, (H - C_{2 π}^{\equiv} C - H)$
hybridisation of carbon = $s p^{3 - 2} = s p$
