I couldn't fit the last organic questions?
I have a benzene ring reacting with ClCCH2CH3 the 1st carbon has an O double bonded to it. the catalyst is aluminum chloride.
I came up with a benzene ring with CCH2CH3 off of it and a double bonded oxygen to that first carbon, I did it like an acylation, but I'm not sure if I should have done alkylation instead and removed that double bonded oxygen.
Answer:
suggest a mechanism for removing the oxygen. where should it go?
and please, learn either to name compounds, or at least write them properly. which is the first carbon atom?? where did u start counting from and how the heck am i supposed to know that??
just write ch3-ch2-cocl, or C=OCl, or even better (C=O)cl or something, ok?
apart from that u r right, it is an acylation, even a Fidel-Crafts acylation and the product is indeed phenyl-ethyl ketone, or properly said 1-phenyl-propanone
Yeah you definitely need to learn to name the compounds.
Apart from that it looks as though you were trying to do a Friedel-Crafts reaction as AlCl3 is mostly used for this. In Friedel-Crafts you are doing an electrophilic aromatic substitution reaction. You use a carbonyl carbon bonded to an R group as well as a halogen, put it in AlCl3 as well as an aromatic ring. You did your chemistry right as you lose the chloride off your propanoyl chloride compound.
The way the reaction works is pi electrons attack an R+ group (wich occurs through loss of the chloride ion) and forms an unstable non-aroamtic system. To regain the stable aromaticity the system loses the extra Hydrogen present and reforms its aromatic system.
You have to be careful when doing Friedel-Crafts alkylations because carbocation rearrangement can occur.
