Answer:

It remains the same.

Explanation:

Physical changes will not affect the number of atoms in a molecule. Dissolving the substance and melting are physical changes which, if they are reversible, will not affect the chemical composition of the molecule.

In the moment in which the physical change is not reversible the molecules may undergo a chemical change and this it will affect the chemical composition. Sometimes when we try melting organic molecules and we end up carbonizing the compound forming carbon and maybe carbon dioxide and water beside other kind of compound that are formed when an organic compound is burned.

Likurg_2 [28]

Answer:

Isopropyl has the specific orientation of being attached to a central carbon atom with two CH3 molecules attached (so in IUPAC naming it can become dimethylethyl), whereas propyl is three carbons all attached in a line branching off the main carbon chain, so it's two CH2 molecules and one CH3 molecule.
