Hello everyone in the question it has been given that which gravy stain can be removed.
00:07
So first of all the gravy stain which is on the clothes can be removed with rubbing it with rubbing the stain with alcohol.
00:26
So the stains are grease like natural and the alcohols is a good de -grazing agent.
00:35
Here alcohol will be a be grazing agent so it is used to remove strains which are greasy the water is two polar so it does not contain any hydropic part so it does not contain any hydrophobic part as well as the gravy strain cannot be removed the hexane is hydrophobic though but it is amphiphilic like the ethanol so ethanol is best so, for the first one, we can say that ethanol is.

So, this is the first part of the question.
01:19
Coming to the second part, the reaction of glycerol, trioliate with bromine, chryolite.
01:30
So let's have a look at the answer.
01:33
So the compound is given as compound here, ch2, 7 single bond c h double bond c h single bone c h 2 taken 7 times and c h 3 so it will be attached to another carbon and this will be attached to another carbon so here is ch2 and hydrogen so here another same type of chain will be present so that is double bonded oxygen c .h2 which is taken 7 times c .h double bond c h and single bond c h2 7 c h 3.
02:24
So here same type of bond will be present it will be with oxygen then double bonded oxygen is present then c h 2 it is taken 7 times c h double bond c h bonded with c h 2 taken 7 times ch3...
