This is a revision quiz haha
1. You have to start counting from the functional group
2. Yes
3. Yes
4. Yes
5. Yes. Also ur school is dumb the syllabus only requires knowing carbon chains up to 8
6. Yes
7. Yes
8. Aromatic means it contains a benzene ring, the question asks for not aromatic
9. I may be wrong but I don’t think the amine functional group can react with hydroxides, the carboxylic acid definitely can though.
10. The equivalence point definitely isn’t 13 (that would imply pretty much only sodium hydroxide). You should just convert to pKb, then to Kb and then use the [OH-] formula to get a value for pOH, which you can use to find pH.
