Newman projection of 3-methylpentane How would you draw the Newman projections of 3-methylpentane, sighting along the C3-C4 bond? I am unsure as to how to position the $\ce{-CH3}$ and $\ce{-CH2CH3}$ groups on the C3.
The Newman projections of 3-methylpentane are:



This is a staggered conformation.
Another one would be

  

This is also a stggered conformation and is the most stable of conformers.

You can generate other conformers by rotating the C-3 or C-4 atom along the C-3 C-4 bond axis.
