Naming substituted branched alkanes with different projections Hi all, I would like some help with naming these two compounds.

For compound 1, I know it is a 2-methyl-pentane, but I am unsure how to name the 3,4 $\ce{OCH3}$ compounds. I know that in the final name, it would be 2-methyl-3,4-di[$\ce{OCH3}$]-pentane (or vice verse depending on alphabetical order.).  

For compound 2, I am absolutely lost and would appreciate any help. At first I though it would be a bicyclic cycloalkane, but I steered away from that idea because of the three bridgeheads. Is it possible to have three bridgeheads? I just learned this content yesterday in class and have scoured through my textbook but have seen no mention of a compound like this one. If you could at least give my a general idea of how the 3D structure looks, that may help me. Thank you!
You are right about the first one, it's called 2,3-dimethoxy-4-methylpentane. The $\ce{-OCH3}$ group is called methoxy. The second compound is a 
newman projection
. It is basically the view that you will see when you are looking down the $\ce{C-C}$ bond axis. The second one should be called 2,3-difluoro-2,3-dimethylbutane. 

Here's what it looks like (http://www.chemspider.com/Chemical-Structure.57499056.html?rid=29f2de9b-b762-46d4-a2ca-7452b8a5d6b6). In the newman projection you are looking down the the C2-C3 axis, and the arms show the substituents bonded to them.
