what happens when a benzene ring reacts with NBS then with NaOH
b) Predict the major product with mechanism when Ethylbenzene reacts with NBS& NBS 2 tl c) Propose the mechanism of this reaction: (2) NBS Be
When there is an electron-withdrawing group on a benzene ring (eg. compounds such as nitrobenzenebenzoic acid, acetophenone, etc, resonance structures can be drawn that indicate the positions on the benzene ring that are least nucleophilic (because they have a positive charge on the carbon at that position). Because these positions are much less nucleophilic, the substitution reaction will not occur here; instead, substitution will occur at the other position(s) on the ring. As a result, which position(s) are most nucleophilic...
When installing a substituent on a benzene ring that already has
2 substituents on it, my textbook says that the stronger activator
will determine where the new substituent is installed. What about
in the case of the a benzene ring that has 2 deactivators? What is
the rule in that case? Does the stronger deactivator determine
where the new substituent is installed? How does that work?
Here is an example of what im talking about:

5) When benzene reacts with isopropyl chloride in the presence of AlCl3, a compound with a molecular mass of 162 g/mol is isolated. In HNMR, this compound has the following spectrum. What is it and why is it formed? PPM
When benzene C6H6 reacts with bromine Br2, bromobenzene C6H5Br is obtained: C6H6 + Br2 --> C6H5Br + HBr (balanced already) When 15.0 g of benzene reacts with excess Br2, 0.19 mole of bromobenzene C6H5Br was produced? IF the actual yield was 42.3 g of C6H5Br produced, Calculate the percent yield.
