Which of the following alkenes is most easily formed by dehydrohalogenation of alkyl halides?

Arrange the following alkenes in increasing order of their enthalpy of hydrogenation $(-\Delta H)$:

The reaction of propene with $HOCl$ $(Cl_2 + H_2O)$ proceeds through the intermediate $:$

The reaction $CH_2 = CH_2 + H_2 \xrightarrow[{250 - 300 \, ^oC}]{{Ni}} CH_3 - CH_3$ is known as:

$6 \ L$ of an alkene require $27 \ L$ of oxygen at constant temperature and pressure for complete combustion. The alkene is.....
