1. Carbon has 6 electrons. When we put a second electron in the orbitals, Hund's
rule states that the electrons should have parallel spins (remained unpaired) if
possible. Add the electrons to the energy level diagram of C.​

4. propanol and isopropanol are isomers. this means that they have a) the same molecular formula but different chemical properties. b) different molecular formulas but the same chemical properties. c) the same molecular formula and the same chemical properties. d) the same molecular formula but represent different states of the compound
