...and i want a pony for christmas. ;)

you have two options

1) read the VMD user's guide and understand how atom selections
    work and then use them to get this information.

2) use your knowledge of chemistry and typical bond lengths and atom
   distances in organic molecules to answer this question directly
    without using VMD.

once you have done either one, you can sit back and realize
that it is not a very good idea to ask a question on public mailing
list to people that volunteer others to help without giving any
indication that you have made some attempts to solve the
problem yourself.


ps.: thanks for providing such a great opportunity revive
a very old - but timely - joke.
