The compound octane, on thermal cracking, will give:
Open in App
Solution
The correct option is D Pentane and propene
The reaction in which hydrocarbons with high molecular masses, on heating in the absence of air, form hydrocarbons with lower molecular masses is known as a thermal cracking reaction.
∙ However, the total number of carbon and hydrogen atoms present in the hydrocarbon with higher molecular mass will be equal to the number of carbon and hydrogen atoms of product present in total.
∙ Octane will undergo thermal cracking to form pentane and 1- propene. The chemical reaction for the same is given below: CH3CH2CH2CH2CH2CH2CH2CH3(g)→CH3CH2CH2CH2CH3(g)+CH3CH=CH2(g)
