22.5 g of chlorobenzene, with a molar mass of 112.56 g/mol, is nitrated…
Contributed by StemPy LabTry it on paper first. A hint, the key idea and the worked solution are here when you need them.
of chlorobenzene, with a molar mass of , is nitrated. The total yield of the mononitro compounds is . Of these, is the para isomer, is the ortho isomer and the rest is the meta isomer. The molar mass of chloronitrobenzene is .
Find the mass of p-chloronitrobenzene and the mass of o-chloronitrobenzene.
Need a reminder? The key ideaShow
A group on the ring directs the next substituent. , and alkyl groups activate and direct ortho and para. Halogens deactivate and direct ortho and para. , , , and deactivate and direct meta. Light and heat attack the side chain. A Lewis acid in the dark attacks the ring.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. Moles. .
Step 2. Mononitro compounds. .
Step 3. Para. . Mass: .
Step 4. Ortho. . Mass: .
Answer: of the para isomer and of the ortho isomer. The halogen directs to both positions, and para is more.
