I'm a little confused about what you mean by "change in temperature values." Do you mean that the boiling point of n-pentane and 1-butanol are significantly different? They do have similar molecular weights (also called molar mass) but 1-butanol has OH attached to it which means that 1-butanol can form hydrogen bonds whereas n-pentane can not form hydrogen bonds. The hydrogen bonds cause the alcohol (1-butanol) to have higher boiling points. The same thing can be observed in the series H2O, H2S, H2Te or in NH3, PH3, AsH3, etc etc. Repost with clarification if I have interpreted your question incorrectly.
sorry this question is out of a lab and i didnt think that nobody would understand the change in temperature since they havent done the lab but that does answer my question.
You're welcome.
