Lewis structures & functional group ID of simple organic compounds Lewis Structure Formula (Identify the functional groups) H �•Ñ…ample: Aldehyde C,H,O3 Carboxylic Acid H 1. CH;CI 2. CH20 3. C2H,O2 4. C2H2 5. C3H6O
The Correct Answer and Explanation is :
- CH₃Cl (Chloromethane)
- Lewis Structure: The carbon atom (C) is bonded to three hydrogen atoms (H) and one chlorine atom (Cl), forming a tetrahedral structure. The chlorine atom is single-bonded to the carbon, with three single bonds to hydrogen atoms.
- Functional Group: Alkyl halide (because of the C–Cl bond).
- CH₂O (Formaldehyde)
- Lewis Structure: The carbon atom (C) is double-bonded to oxygen (O) and single-bonded to two hydrogen atoms. The carbon is in the center, with two single bonds to hydrogen and one double bond to oxygen.
- Functional Group: Aldehyde (because of the C=O double bond and C–H bond at the end).
- C₂H₄O₂ (Acetic Acid)
- Lewis Structure: The molecule consists of a two-carbon backbone. One carbon is double-bonded to an oxygen atom and bonded to a hydroxyl group (–OH), while the other carbon is single-bonded to the first carbon and bonded to a hydroxyl group.
- Functional Group: Carboxylic acid (because of the –COOH group).
- C₂H₂ (Acetylene)
- Lewis Structure: The two carbon atoms are triple-bonded to each other, with each carbon also bonded to one hydrogen atom.
- Functional Group: Alkyne (due to the C≡C triple bond).
- C₃H₆O (Acetone)
- Lewis Structure: The carbon chain consists of three carbons, with the middle carbon doubly bonded to an oxygen atom (forming a carbonyl group) and single-bonded to two other carbons (one of which is bonded to a hydrogen atom).
- Functional Group: Ketone (due to the C=O group).
These structures are a basic approach to organic functional group identification. If you’d like more detailed or visual depictions, I can generate images or draw the Lewis structures for you! Let me know how you’d like to proceed.
