### Organic Chemistry: Structure Drawing Exercise **Question:** Draw out the structure of the following molecules. 1. **4-chlorobenzoic acid** 2. **2,4-dimethylpentanal** 3. **cis-1-bromo-3-isopropylcyclopentane** 4. **ethyl 3-ethylhexanoate** ### Explanation and Guidelines: 1. **4-chlorobenzoic acid:** - **Structure:** 4-chlorobenzoic acid is a benzene ring with a chloro group (-Cl) attached to the fourth carbon (relative to the carboxyl group, -COOH) in the ring. 2. **2,4-dimethylpentanal:** - **Structure:** This molecule is a pentanal chain (5 carbon atoms with an aldehyde group, -CHO, at the end) with methyl groups (-CH3) attached to the 2nd and 4th carbons. 3. **cis-1-bromo-3-isopropylcyclopentane:** - **Structure:** A cyclopentane ring (5 carbon atoms in a ring) with a bromo group (-Br) attached to the 1st carbon and an isopropyl group (-CH(CH3)2) attached to the 3rd carbon. The "cis" configuration means both substituents are on the same side of the ring plane. 4. **ethyl 3-ethylhexanoate:** - **Structure:** This is an ester formed from hexanoic acid. The main chain is hexanoate (6 carbon atoms) with an ethyl ester group (-COOEt) and an ethyl group (-CH2CH3) attached to the 3rd carbon. ### Notes: - **Structural Drawing Tips:** When drawing these structures, ensure correct connectivity and placement of functional groups. Pay attention to the stereochemistry ('cis' configuration) and proper labelling of carbon atoms according to IUPAC naming. For further reference, visual aids such as molecular model kits or software tools can be very useful for understanding and drawing these complex structures.
