(CH3) 2CHCH2CH3   alkanes   1-methylbutane
thats what answers say :S

I just drew it and it's definitely 2 methyl butane. Must be a typo in the book.

For reactions involving hydrocarbons, most are gases at room temperature

For substitution reactions (chlorination, bromination, fluorination, etc) with 7th group elements, they will be gases until about C7H16 until they turn to liquids, and then to solids at roughly C70H142. This remains true unless the question tells you that they react in solution.

e.g. CH3CH2(3)CH3(g) + Cl2(g) --> CH3CH2(3)CH2Cl(g) + HCl(g)

However, alcohol substitutions are likely to become aqueous liquids for the majority of alkanol syntheses. Reactants are likely to be gases, and the alkanol product will be aqueous.

Carboxylic acids are almost always going to be aqueous or liquid in state.

Amino groups are rarely gases.
