Plastic is man-made. It's a hydro-carbon compound.
As organic chemistry is that which involves carbon-based compounds, and as almost all plastics contain carbon, most plastics are organic.
No, plastic is man made

Synthetic materials are any materials that do not occur naturally and are man-made, usually by chemical processes. These can include a huge range of materials including plastics, nylons, ceramic materials and even some metals.
94 kinds of atoms occur naturally on earth
Chlorine gas does not occur naturally as it is too reactive. Chloride salts occur naturally. The most common is sodium chloride, NaCl. Chlorine, Cl2, is obtained by electrolysing molten NaCl.
Yes, it occurs naturally on earth.
yes,it does
