You should be able to make the graphs(to be turned in with the report) and answer the questions from theabove data.
MAKE A PLOT OF CHange of Temp vs the number of carbons in thecompound for the alkanes.
a) using the concept of IMFs, explain WHY you see the trend yousee. Give explanation using specific IMF names.
b) What would your prediction be for the change in temp fordecane? Show how you determined this.
