I have a mixture containing the following three compounds: 0.20g o-toluic acid, 0.25g fluorene, 0.05g of 1,4-dibromobenzene. I'm required to separate (any) two of of the three. Please could some one help me with how I'd separate two of the three above named compounds.

JUST FOR CLARIFICATION - I only have the chemicals listed below to isolate two of the above mentioned compounds and we can only use crystallization and extractions to do so,. I know there are many different ways to perform an extraction, we've only learnt to make a mixture that has two immiscible layers, remove one and dry with sodium sulfate. I am eager to learn more ways, but, for this question if an extraction is required for one or more of the chemicals could you use the way i've learnt so far.

Chemicals available for extractions: CH2CL2, 1M NaOH, 1M HCL and sodium sulfate for drying

Chemicals available for crystallization: ethyl ether, 95% ethanol, methanol, isopropyl alcohol, acetone, hexane, toluene and methylene chloride.

Thanks in advance!

I am stuck on this mechanism ... what i have done is firstprotonate the double bonded O on the carboxylic acid and then donean intramolecular attack from the ether in the ring and formulateda plus charge on that O wiich is attached to a carbon that has twoalcohols and another carbon that is attached to the O-R group andthen the carbon that is attached to the ring.. I am sorry myexplanation of where im stuck is not well written.. please help inany way.. and i am not sure if i have even made the correct initialsteps.


THANKS SO MUCH FOR ANY HELP


Greetings,

I am VERY confused and need someone to simplify this example forme.I will be so grateful and rate lifesaver for sure!! My commentsarebelow the parts, but I do not understandwhy the answeris what it is.

The molecule in question SO2.

A. What is the lewis structure?

I understand that SO2 has 9 pairs of lone pairs. Sulfur is inthecenter and must have an octet. But, how do you know when tostartadding double bonds? And where? Why?

B. What is the shape?

I thought it was linear because the spacial arrangements need tobefar apart as possible? But it is bent? Wouldn't a bent moleculeinthis case make the lone electrons closer, than further apart? IamSO confused on this...Is there an 'easy' way on how to tellwhenthe electrons are furthest apart? For some reason, I'm having alotof trouble with this seemingly simple concept.

C. Is there a dipole moment?

I thought there would be no dipole moment because oxygen ismoreelectronegative than sulfur and the vector would cancelout.However, in the answer there is one with the dipolepointingdownward from the Sulfur. Again, very confused!!
