making a conclusion by observing a model\nanalyze the polymer polypropylene.\nwhich element forms the skeleton of this polymer?\ncarbon\ncopper\nhydrogen\noxygen
Answer
Brief Explanations:
Polymers like polypropylene have a carbon - based backbone. Carbon atoms bond together to form the long - chain structure which is the skeleton of the polymer. Other elements like hydrogen are attached to the carbon atoms. Copper and oxygen are not the main elements forming the skeleton of polypropylene, and hydrogen is a side - attached atom rather than the backbone - forming atom.
Answer:
carbon
