Question
Hello, I do not understand these questions for chemistry and I am stuck. May I get help please please?? An explanation leading to steps would be helpful. Thank you. Question: Draw the MAJOR organic product(s) for the following reactions. If no reaction occurs, state ‘no reaction’ in the box provided.
### Description of Chemical Reactions: #### Reaction a: 1. **Starting Material**: - The molecule is a bromomethylbenzene (a benzene ring with a CH2Br group attached). 2. **Reagents**: - 1. **Mg**: This typically indicates the formation of a Grignard reagent. - 2. **CO2**: Carbon dioxide is used in reactions with Grignard reagents to form carboxylic acids. - 3. **H3O⁺**: Acidic work-up step, generally used to protonate the intermediate product. 3. **Expected Outcome**: - The bromomethylbenzene will form a Grignard reagent with Mg. - This reagent will subsequently react with CO2 to form a carboxylate intermediate. - The acidic work-up with H3O⁺ will protonate the intermediate to yield a carboxylic acid. #### Reaction b: 1. **Starting Material**: - The molecule is an ester (an acetyl group attached to an ether group). 2. **Reagents**: - **NaOH**: Sodium hydroxide is a strong base used in saponification reactions. 3. **Expected Outcome**: - The ester will undergo saponification in the presence of NaOH to produce a carboxylate salt and an alcohol. #### Diagram Explanation: - There are two rectangular boxes representing the products of the respective reactions. - The first box is for the product of Reaction a, expected to be a carboxylic acid. - The second box is for the product of Reaction b, expected to be the carboxylate salt and alcohol resulting from the saponification of the ester.
