First, I don't understand the major difference between a conformation and an isomer. Below are the definitions that I found. They both sound the same, all I can see is that a re-arrangement takes place in BOTH of them.
Conformation is any one of the infinite number of possible arrangements of atoms in a molecule that result from the rotation of atoms around single bonds. Conformations of a molecule are not isomers, but merely twisted versions of the original molecule.
Isomers are molecules with the same molecular formula, but different structural or spatial arrangements of the atoms within the molecule.
It is this lack of understanding that is preventing me from answering the below questions:
Is molecule B a conformer or isomer of Molecule A? ( I think conformer because per the definition, atoms are rotating around single bonds, but technically is the molecular formula the same making it an isomer?)
Is molecule C a conformer or isomer of Molecule A? ( I think conformer because per the definition, atoms are rotating around single bonds, but technically is the molecular formula the same making it an isomer?)
