Answer:
This pair of molecules are cyclopentane and pentane.
Explanation:
The white balls represent hydrogen atoms while the black balls constitute carbon atoms both for configurations. While each hydrogen atom can only really attach to just one other atom, each carbon atom can connect to 4 other atoms. The first one, therefore, therefore consists of a cycle comprising 5 carbon atoms, each of which is linked to 2 additional carbon atoms as well as to 2 hydrogen atoms. This substance is known as cyclopentane.
Because the balls are joined one after another, the next one is just a linear molecule. It has 3 hydrogen atoms connected to the terminals of two carbon atoms plus 2 hydrogens bonded to each of the 3 separate carbons. The name of such a molecule is pentane.
