Exam questions on Naming organic compounds with IUPAC rules

A chemist is labelling bottles in a laboratory store. Every organic compound must carry its IUPAC name, in which the stem shows the number of carbon atoms in the longest chain and the ending shows the family of the compound.
Give the name of CH₃CH₂CH₂OH and state what the ending -ol shows about the compound.2 marks
A student is studying 2-methylpropane, which has the molecular formula C₄H₁₀ and the condensed structural formula CH₃CH(CH₃)CH₃.
Explain what the parts 'propane' and 'methyl' tell you about the structure of 2-methylpropane.2 marks
