what is the name of (ch3)2chch2ch(ch2ch3)ch(oh)ch2ch3

Answer 1

I am not an organic chemist but I would name this as
2-methyl-4-ethyl-5-hydroxy heptane but you should get a second opinion.

Answer 2

Here is my shot at it.

4-ethyl-6-methyl-3-heptanol or 4-ethyl-6-methyl-heptan-3-ol

Hydroxyl groups takes precedence.

There are many tutorials on the web that can help

Answer 3

Naming it as an -ol makes sense to me.

Answer 4

The compound is an alcohol. Google IUPAC and alcohols and maybe it will make since.

Answer 5

Sense, not since. I apologize, autospell.
