Question

Combustion of which of the following compounds ( in the presence of excess of oxygen) does not result in the change in the hybrid state of cabon atom?
A. `CH_(4)`
B. `CH_(2)=CH_(2)`
C. `CH_(3)-CH_(3)`
D. HC=CH

Answer 1

Correct Answer - D
`underset("Acetylene")(HC-=CH+5//2O_(2))to underset("Carbon dioxide")(2O=C=O+H_(2)O)`
In acetylene each C atom is sp-hybridised. Similarly in carbon dioxide, C-atom is sp-hybridrised
