Hi Surya,
Using the interactive builder is usually the way to go. To get you started
you may need a starting atom, which you could create using the pseudoatom
command:

Note that the builder has some templates, e.g. the cyclopendadiene that you
can use
Hi Surya,
I don't know exactly what problem are you experiencing (I tried to do
something similar without any problem). I guess that maybe the problem is
that when you are rebuilding the ring, you are positioning the atoms in a
not very good position and maybe PyMOL is having trouble to figure-out
