HSC Chemistry — Module 7
Functional Groups — Flashcards & Quiz
Functional groups are the reactive sites that define organic chemistry, and recognising them is essential for HSC Chemistry Module 7. You need to identify alcohols, aldehydes, ketones, carboxylic acids, esters, amines and amides from structural formulas, and predict how each affects physical properties such as boiling point and solubility. IUPAC naming follows directly from group identification — practise reading a structure, finding the highest-priority group, and assigning the suffix. Group recognition is a free-mark builder when you are confident.
Sample Flashcards
Q1: Name the main functional groups studied in HSC Chemistry.
Hydroxyl (-OH): alcohols. Carboxyl (-COOH): carboxylic acids. Ester (-COO-): esters. Amine (-NH₂): amines. Amide (-CONH₂): amides. Carbonyl (C=O): aldehydes (-CHO at end) and ketones (C=O in middle). Halogen (-X): haloalkanes.
Q2: What is the difference between an aldehyde and a ketone?
Both contain the carbonyl group (C=O). Aldehydes have the C=O at the END of the carbon chain (bonded to at least one H). Ketones have the C=O in the MIDDLE (bonded to two carbon groups). Aldehydes can be oxidised to carboxylic acids; ketones cannot.
Sample Quiz Questions
Q1: The -COOH group is called a hydroxyl group.
Answer: FALSE
The -COOH group is a CARBOXYL group (found in carboxylic acids). The -OH group alone is the HYDROXYL group (found in alcohols).
Q2: Aldehydes have the carbonyl group at the end of the carbon chain.
Answer: TRUE
Aldehydes have the -CHO group at the end of the chain. Ketones have the C=O group in the middle of the chain.
