Thank you so much. It makes sense NaOH and ether will sepearte biphenyl from Fluorene because biphenyl will stay in ether phase. If I understood this earlier, then I would have got the right answer for my lab. Well, Still I'm so happy that I know now. Thank you again!

Thanks for help, It's kind of still confusing becaue the question is asking about to purify the biphenyl from fluorene.

Homework Statement what would be the good method and solvent to purify biphenyl contaminated with fluorene? Homework Equations The Attempt at a Solution The polarity of biphenyl (MP: 68.93°C) and fluorene (MP: 116-117°C ) are same which is non polar but their MP is hugh...

I don't think sodium benzoate dissolves in methylene chloride becaue methylene chloride is organic compound and non polar. Other acids such as benzoic acid and succinic acid dissolves mostly in Water because they are di-polar but still dissolves tiny amount in methyle chloride.

if you are referring to sodium benzoate, it dissoloves in water completely becaue of the inonic bond, I think.

Homework Statement Hey guys, I have lab result here for Distribution of coefficient for the solid between water and metylene chloride Benzoic Acid: 5mg (Weight of solute in methylene chloride) 45mg (Weight of the solute in water ) Succinic Acid...

Chemisttree, Thank you so much! I agree with you it is impure due to the lower melting point. I was confuse with equlibrium. It was so helpful!

Homework Statement In the reaction between salicylic acid and acetic anhydride, if you use a water bath at 90°C instead of 50°C. The final product (acetylsalicylic acid) was tested for the presence of phenols with ferric chloride. This test was negative (no color observed); however, the...
