3. Постройте структурные формулы двух изомеров, соответствующих составу С9Н16. Назовите полученные вещества. К каким классам (классу) они относятся?

I don't have the ability to generate images or draw chemical structures, but I can provide you with the names and classes of the isomers corresponding to the formula С9H16.

One possible isomer is called 2-methylheptane (2-метилгептан). It belongs to the class of alkanes (алканы).

Another possible isomer is called 3-methylhexane (3-метилгексан). It also belongs to the class of alkanes (алканы).

Please note that there may be additional isomers for the given chemical formula, but I am unable to generate their names or structures.
