Which of the following solvents can hydrogen bond?
diethyl ether |
||
hexa-2-one |
||
pentanal |
||
chlorobenzene |
||
butanol |
butanol
Butanol having -OH (hydroxy) functional group in it.
Hydrogen attached to electronegitive atom (here oxygen) can forms hydrogen bonding.
So, butanol forms hydrogen bond

Diethyl ether is a good solvent to be used with Grignard reagents. Which of the following explanations for this laat alle! It can serve as a Lewis base and stabilize the Grignard reagent. It has a very high boiling so it can be heated to drive the Grignard formation to completion. It is polar enough to stabilize the Grignard reagent. It is aprotic and thus is not acidic enough to react with the Grignard reagent.

decided to carry out the synthesis using diethyl ether as the (Due to its low boiling point diethyl ether is a good, though highly flammable, bulk solvent for many organic reactions because it is readily removed from the reaction mixture.) She placed the appropriate mass of -butené in the diethyl ether solvent, then added MBr to start the reaction. She isolated a product and obtained a proton NMR spectrum for the sample. The spectrum that appeared on the screen...
