Contributed by StemPy LabTry it on paper first. A hint, the key idea and the worked solution are here when you need them.
Methanol, , has a molar mass of . Use the rule of a homologous series to find the molar mass of hexanol, . Check it by adding up the atomic masses. (, , .)
Need a reminder? The key ideaShow
Alkanes are saturated, , names ending in -ane. Each member of a homologous series has one more , , than the one before. Boiling points rise along the series. Isomers have the same formula and different structures.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. By the rule. .
Step 2. By the atoms. .
Answer: , the same both ways.
