Steam distillation

Steam distillation may be used to separate a mixture of p-nitrophenoln and o-nitrophenol. The ortho isomer distills at 93 degrees Celsius, the para isomer does not. Explain

Butanols

Which of the isometric butanols(C4H10O) can be prepared by reduction of a ketone with sodium borohydride?

Ultra-microscale boiling point

When determining ultra-microscale boiling point, materials that are thermally stable at their boiling point do not give identical values on repeat determinations. True or False?

Predict the major organic product

I need a lab procedure for separating the following compounds, using the following reagents.

I will be given 3 compounds in a mixture, which must be separated and varified by melt point. I will have 1 of each of the following sets (either Benzoic or Salicylic Acid),(either 2-Naphthol or Phenol)(either Biphenyl or Naphthalene). I have been told I can do this using a seperatory funnel for an extraction. The resulting sepa ...continues

provide a synthesis

Provide a resonable synthesis for compound P starting from O. You may utilize any organic reagents that contain three or less carbons, as well as any inorganic reagents.

organic chem

Match the descriptors on the left with the correct reaction mechanism on the right by placing the appropriate letter from the column. Some can have more than one letter for answer. 1. The product is an alkene. 2. Inversion of configuation occurs. 3. Apolar aprotic solvent is best. 4. Methyl>1 >2>3 %A carbocation is involved. ( ...continues

H NMR

Could you let me know whether the answers I have provided is correct. The last question (part c) is giving me some problems. thanks ps see attached document.

H NMR

Could you review my solutions and let me know if I'm on the right track. thanks Ps. see attached file. Yes, the last two pages are suppose to be blank.

H and C-13 NMR

I'm having some problems identifying the unknown compound based upon the information given. I provided as much information as I can with a possible compound, but I don't think it's correct. Can you check over my solution, please thanks ps see attached file.
