ah yes, my bad, its a trigonal planar molcule because it has a double bond, so each carbon is bonded to essentially 3 other atoms (count the C=C double bond as one bond)
C2H3CL is Chloroethene. Its got a double bond between the carbon atoms.
I can see why its 120 degrees between each bond because the carbon atom has one double bond and 2 single bonds coming off it. Therfore for maximum seperation - 120.

so 3 bonds = trigonal planar = bond angle of 120
This could be misleading when it comes to lone pairs of electrons.
My bad, Carbon has 4 not 5 electrons, so it would be slightly smaller than a triganol planar shape so about 119.
Having 4 bonds and no lone pairs would make it 107 degrees not 119. Because of the double bond with the neighbouring carbon atom you get "3 bonds" if you must in the carbon atoms. Thus the bond angle around each carbon atom is 120 degrees so it must be a trigonal planar.
