Can I please get help with this?

1. Draw structures corresponding to each of the following names [3 ONLY]: A. 2,2,2-trichloroethanal (chloral). B. trans-3-isopropylcyclohexanecarbaldehyde C. What is the correct structure for 2-hydroxyacetophenone? Circle the letter of your response. a C 0 OH OH OH HO b. H3C CH 0 H d OH D. Provide IUPAC names for each structure below. 0 H C-H 0 0 CH3 H NO₂ E. The substance formed on addition of water to an aldehyde or ketone is called a hydrate or a/an: a. vicinal diol b. geminal diol C. acetal d. ketal

2. Consider the data below to answer the following questions. Cyanohydrins are important intermediates in the synthesis of α-hydroxycarboxylic acids from ketones and aldehydes. The nitrile functional group can be hydrolyzed by aqueous acid to yield a carboxylic acid. Nitriles can also be hydrolyzed to carboxylic acids using aqueous base. Unfortunately, when a cyanohydrin is treated with aqueous base the original carbonyl compound is isolated. OH CH-COOH 0 HO CN C H30* C. H H HC N NaOH H₂O C=O 0 cyanohydrin H + NaCN + H₂O

- Consider the data in the Table below to answer the following questions: Acidities of Substituted Benzoic and Acetic Acids pk,s at 25C Y-CH COOH Y Y - CH₂COOH meta para H 4.75 4.19 4.19 2.47 3.64 3.55 3.57 4.09 4.46 CN OCH 3 A. Draw the structure of the strongest acid in the table above. B. Explain why cyanoacetic acid and methoxyacetic acid are more acidic than their correspondingly substituted benzoic acid counterparts.

Draw the curved arrow mechanism for this reaction starting with 2-propanol in sulfuric acid. Show all nonzero formal charges and all nonbonded electrons in each step. Species not involved in a particular step do not need to be included in that step, and resonance forms do not need to be shown. Note that the alcohol is in much higher concentration than H₂O in this reaction. H
