Question:

what are five ways in which pentane, 2-methylbutane, and 2,2-dimethylpropane are similar?

Answer:

These three compounds given have the following formulas:

Five ways, in which they are similar, are:

1) firstly, they all belong to the same class of organic compounds – alkanes ( saturated compounds with general formula $C_nH_{2n+2}$ );

2) secondly, they contain the same number of carbon atoms - five;

3) moreover, all of them have the same brutto-formula: $C_5H_{12}$ ;

4) in addition to this, these all compounds are acyclic (doesn't contain cycle fragments);

5) to conclude, they give the same compounds in the reaction with $\mathbf{O}_2$ :

$$\mathrm {C} _ {5} \mathrm {H} _ {1 2} + 8 \mathrm {O} _ {2} = 5 \mathrm {C O} _ {2} + 6 \mathrm {H} _ {2} \mathrm {O}$$
