Vedclass · Answer

(C) The heat of combustion is directly proportional to the number of carbon atoms in the molecule for homologous series. For isomers,it is inversely proportional to the stability of the molecule.$(A)$ The image shows alkyl-substituted cycloalkanes. The heat of combustion increases with the number of carbon atoms.$(B)$ The image shows bicyclic compounds. The heat of combustion increases with the number of carbon atoms.$(C)$ For isomers of butene $(C_4H_8)$,the stability order is $trans-2-butene > iso-butene > 1-butene$. Since heat of combustion is inversely proportional to stability,the order of heat of combustion should be $1-butene > iso-butene > trans-2-butene$. Thus,the statement $Iso-butene > trans-2-butene > 1-butene$ is incorrect.$(D)$ For $n-alkanes$,the heat of combustion increases as the number of carbon atoms increases $(n-Hexane Therefore,the incorrect statement is $(C)$.
