How is anthracene insoluable in water but soluable in methanol ? (Base your explanation on the strucutre of the compound)
Homework Answers
Ans. Water is a polar solvent. As polar solvents dissolve only polar solutes or molecules having polar rations, water can’t dissolve non-polar anthracene. In insolubility of a non-polar solute (here, anthracene) in polar solvent (water) is attributed to the unfavourable intermolecular interactions (or, better say, absence of favourable intermolecular interactions like ionic interactions, h-bonds, etc.) between the solvent and solute molecules.
# Methanol is also polar because of presence of –OH group. However, it also has a methyl group (-CH3) as a non-polar group/ region. The non-polar –CH3 group favourable interacts with non-polar anthracene (through weak van der Waals interactions). Therefore, due to similar polarity, anthracene exhibits solubility in methanol solvent.

I did an organic chemistry lab using the Diels-Alder reaction with anthracene-9-methanol, N-methylmaleimide, and water. I started with 0.066 g of anthracene-9-methanol, 25 mL of deionized water, and 0.070 g of N-methylmaleimide. How would I calculate the percent recovery of the product? (not the percent yield)

Anthracene -9-methanol and 3 equivalents of N-methylmaleimide were mixed with water in an Erlenmeyer flask and heated to reflux( Diels-Adler reaction) TLC was prepared using a 1:1 ratio ethyl acetate: hexane. We got Rf=0.8 for N-methylmaleimide Rf=0.6 for anthracene and Rf=0.3 for the mixture. What information does this provide?

how do I know if a compound is a base or an acid just by looking at its formula? i know how to determine acid and bases based on the whole equation, but it is hard to know just by looking at the compound, for example, Hco3, is it a base or an acid and how do we know, are there steps I can use? please give me examples with the explanation when I look at the formula for Hco3,...

3. Shown below is a compound that is soluble in methanol (CH3OH). Show how methanol would act as a solvent for this compound (show two methanol molecules, one acting as an acceptor and the other acting as a donor). Lone pairs of electrons are should be shown on all atoms that contain them. A complete answer would include drawing the Lewis structure for the compound shown below H_CC(CH3)OCH(OH)NH2
