The Light Alcohols in Table 16 $\mathrm { C } _ { n } \mathrm { H } _ { 2 n + 1 } \mathrm { OH }$

question 18

Essay

The light alcohols in Table 16.1 are referred to as monohydric alcohols and have the formula $\mathrm { C } _ { n } \mathrm { H } _ { 2 n + 1 } \mathrm { OH }$ . Common heavier monohydric alcohols are pentanol $( n = 5 )$ and cetyl alcohol $( n = 16 )$ .
(a) Write the formula for the combustion of pentanol and cetyl alcohol.
(b) Calculate the mass of $\mathrm { CO } _ { 2 }$ produced per $\mathrm { kg }$ of alcohol for these two materials.
(c) Locate values for the heat of combustion for these two compounds and calculate the mass of $\mathrm { CO } _ { 2 }$ produced per $\mathrm { MJ }$ of energy. Comment on the trend which is shown in these results.
