Vedclass · Answer

(D) The general formula for alkanes is $C_nH_{2n+2}$.Decane has $n = 10$,so its formula is $C_{10}H_{22}$.Undecane has $n = 11$,so its formula is $C_{11}H_{24}$.The difference between the two is one $CH_2$ group.The molar mass of a $CH_2$ group is $(1 	imes 12.01) + (2 	imes 1.008) \approx 14.02 \ g \ mol^{-1}$.Rounding to the nearest whole number,the difference is $14 \ g \ mol^{-1}$.

What is the difference in molar masses of Undecane and Decane?
