Which solvent should you use to separate benzoin from benzil?
HNO3= nitric acid
What is solvent for benzil to develop TLC and Rf?
50:50 ethyl acetate and petroleum ether gives an rf value of about 0.6.You are supposed to dissolve the compound in any volatile solvent like methylene chloride or acetone.
Why use KOH in benzilic acid rearrangement?
KOH act as a nucleufeel and react with benzil OH give electrones to benzil and berak the double bond.
Do petroleum ether and methanol mix?
No, one is polar, the other is non polar
How do you get a better yield of benzil quinoxaline?
add water
Arrange the following compounds in order of increasing Rf values in TLC Anthracene benzil tryphenylmethanol?
The order of increasing RF values in TLC is Benzil, methanol anthracene and tryphenyl.
Does benzil react with Naoh?
C6 - H5 - CH2 - OH + NaOH = C6 - H5 - CH2 - O- Na+ + H2O
What do you get when you mix 5-bromo-1-pentanol with sodium hydride in diethyl ether?
The alcohol is first deprotonated by strong base to generate allxodide ion, which undergo SN2 reaction to the product cyclic ether.
Is benzil a polar molecule?
It might be tempting to think Benzil is a polar molecule because of the C=O bonds, but the high level of symmetry in the molecule cancels out any overall dipole and leaves the molecule non-polar.

Why does dilantin have a smaller retention time in reversed phase HPLC as compared to benzil?
My guess is that it is because Dilantin has two benzyl substituents on one carbon, adding steric hindrance. Second, the ring is very electron deficient, and so unstable. Benzil has less steric hindrance and is linear.
