Assume the functional groups below are attached to a benzene ring. Circle the functional groups that are activating. Put a triangle around those that are deactivating. Predict the directing effect of each group (either o,p or m). Do you see any trends? {-Br 4-CF3 OCH3 {NH2 & NH3 NO2 &-coh 10
We saw in this experiment that an ester group with the carbonyl carbon attached to the benzene ring serves as a meta-director, resulting in methyl Meta-nitrobenzoate as the major product of the reaction. Given that a methoxy (-OCH_3) group attached to the benzene ring serves as an orthopara director, draw the major products of the reaction shown below. Use your pre-lab lecture notes to answer this question. Explain using the resonance structures (referred to as the "sigma complex") why the...
(V) 10pts. When aniline (C6H3-NH2) reacts with bromonium ion (NO2. the nitro group can become bonded to a carbon at one of the three possible positions: ortho, meta, and para to the -NH2 group in the benzene ring. Consider meta and ortho attack and draw RESONANCE STRUCTURES for the carbocations that result when NO2 undergoes electrophilic aromatic substitution to aniline. Then, on the basis of these resonance structures, explain whether the --NH2, group.is meta director, or ortho/para director. Show which...
which of the following substituents will stabilize the charge on the carboxylic acid on the benzene ring created during hydrolysis. And why? 1. methyl group at the para postion to the carboxylic group on the benzene ring 2. methyl group at the meta position to the carboxylic acid group on the benzene ring 3. methoxy group at the meta position to the carboxylic acid group on the benene ring 4. methoxy group at the para position to the carboxylic acid...
Banana oil, AKA isopentyl acetate, contains the ester functional group (like methyl benzoate). What products are formed if isopentyl acetate is treated with a huge excess of water in the presence of a dilute acid catalyst? Briefly explain. You will need to look up the structure of isopentyl acetate. Your answer should include a balanced reaction
2. Amino Acids a.) Which amino acid is this: A substitution on the methyl group of this amino acid with a hydroxyl group yields the amino acid Ser and substitution with a phenyl group yields the amino acid Phe. b.) Which amino acid has an a-amino group that is bonded directly to two C atoms, forming a ring?
Benzene has a hydroxyl group attached to the ring. True or False
If a benzene ring has one methyl group as a substituent, will the next substituent add to the benzene ring in the ortho, meta, or para position? Select one: a. para or meta b. para only c. meta only d. ortho only e. ortho or meta f. Ortho or para
In a phenol, which group is the substituent on the benzene ring? a. carbonyl ]b alcohol C carboxyl d amino ts 4 ?
Question 18 (4 points) Friedel-Crafts acylation reactions cannot be performed on aniline because: The amino group gets acylated instead of the aromatic ring. The amino group attacks the Lewis acid to form an acid-base complex in which the aromatic ring is strongly deactivated. The amino group is strongly activating and multiple substitutions occur on the aromatic ring. The amino group is strongly deactivating preventing any substitution on the aromatic ring.
