Cannot easily "draw" on this platform, so here is a description of the Lewis dot structures.
Chlorine: Cl2
Cl - Cl each Cl has 3 lone pairs around it (14 total electrons)
Methane: CH4
Put C in the center with 4 H's around it bonded with single bonds (8 total electrons)
Oxygen: O2
O = O each O has 2 lone pairs around it (12 total electrons)
Nitrogen: N2
N ≡ N each N has 2 lone pairs around it (14 total electrons)
