Vedclass · Answer

(D) Stability in alkanes is generally governed by the heat of combustion per $CH_2$ group and the degree of branching. For straight-chain alkanes,as the chain length increases,the stability per carbon atom increases slightly due to the decrease in the relative contribution of end-group effects. Among the given options,$n$-butane $(C_4H_{10})$ has the longest chain and the highest molecular weight,making it the most stable compared to methane $(CH_4)$,ethane $(C_2H_6)$,and propane $(C_3H_8)$.
