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!

• The O-CH3 group is methoxy. So I think the name of the first compound would be 2,3-dimethoxy-4-methyl-pentane. – MaxW Sep 17 '16 at 20:09
• The circle in the second molecule is looking down a carbon-carbon bond. The solid "Y" are the three atoms/groups bonded to the front carbon, the "broken Y" is for the three atoms/groups on the back carbon. Can you name it now? (This drawing method is used to show stereostructure.) – MaxW Sep 17 '16 at 20:11

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.
