Draw two Lewis structures for C2H6O.C2H6O

a. Draw two Lewis structures for
C2H6O.C2H6O.

b. Draw three Lewis structures for
C3H8O.C3H8O.
(Hint: The two Lewis structures in part a are constitutional isomers—molecules that have the same atoms but differ in the way the atoms are connected. The three Lewis structures in part b are also constitutional isomers.)
