Rusty in general chemistry and need help

[jayb44566]

Hi. It's been since 2007 since I was aquatinted with anything chemistry but I'm trying to find out the following: what are things I have circled in the pic below and how do I synthesize them? Thanks

If the atoms aren't denoted, I think they are assumed to be carbon atoms.

The cross thing is a tertiary butyl group: (CH₃)₃C-.

The leg thing is an n-propyl group: -CH₂-CH₂-CH₃.  

As for how you synthesise them, that rather depends on what you are starting from. You can buy things like t-butyl alcohol or t-butylamine, or n-propanol etc.  

From your question, it seems as if you have part of the molecule already and you want to bolt these groups on. If so, what is the part of the molecule you have got?

How do you know that? Are the actual shapes a standard convention for those groups?

Yes, more or less. I'm doing what you suggested and counting the carbon atoms, then applying the normal organic chemistry convention that all unwritten bonds to carbon are occupied by H. So a zigzag line will be a chain of -CH₂- units, for example, with a methyl group on the end because of the extra bond.

Right. Thanks. Yes, that makes good sense. I forgot about placing the unused carbon  bonds and what might be on them: hydrogen.
