9. A mixture (solution) of 3 different liquid compounds is formed. Each compound has the same condensed formula of C4H10O. Separate analyses of these compounds confirmed that none of the compounds has branching of C’s from the main chain of attached C atoms. Also one of the compounds experiences a weaker interparticle force as its dominant force than the other two. (a) Draw 3 possible preferred Lewis structures consistent with the above formula and information. It is desired to separate...
