Organic Chemistry Exercises: Identifying Functional Groups and Interpreting Spectra, Exams of Nursing
A series of multiple-choice questions and answers related to organic chemistry, focusing on the identification of functional groups in hydrocarbons and the interpretation of spectroscopic data. it tests knowledge of key concepts such as alkanes, alkenes, aromatic hydrocarbons, esters, ketones, and carboxylic acids. The questions require students to analyze chemical structures, identify functional groups, and interpret ir and mass spectra to determine the identity of unknown compounds. This resource is valuable for students to self-assess their understanding of organic chemistry principles and practice problem-solving skills.

Question 1 Hexene is a hydrocarbon containing (#) carbons and a (type) bond. Your Answer: 6 C=C double Question 2 The compound below is a type of hydrocarbon called a/an. Your Answer: aromatic hydrocarbon Question 3 The compound below is called (#s)-dimethyl. Your Answer: 1, cyclohexane
Question 6 The reaction shown below is a/an type reaction. CH 3 CH 2 CH=CH 2 + 6 O 2 → 4 CO 2 + 4 H 2 O Your Answer: oxidation Question 7 In what type of reaction is a hydrocarbon converted to CO 2? Your Answer: oxidation Question 8 The following is a spectrum. Your Answer: mass
Question 9 The compound most likely to have given the SEM/EDS shown below is.
- NaNO 3 2. NaHCO 3 3. NSO 2 4. NaHSO 4 The compound most likely to have given the SEM/EDS shown below is NaHSO 4 H is not detected by SEM/EDS
Your Answer: b. ketone Peak location and bond:
- 3000 - 2800 cm-^1 peak for C-H bond
- 1750 - 1650 cm-^1 peak for C=O bond
- no peak at 2900 - 2700 cm-^1 so no O=C-H bond, not an aldehyde The organic compound is B (ketone) The 3 most important absorption peaks and the bond deformations they describe are:Approximate peak location Bond 3000 - 2800 cm-^1 alkane C-H (stretch) 1720 cm-^1 C=O (stretch)
1460 cm-^1 C-H (bend) or 1375 cm-^1 C-H (bend)
