Identify functional groupsClassify reaction typesApply the oxidation ladderWrite an esterification equation📚 Quick Recap
🎯 What you'll practice: The ten key functional groups, substitution/addition/oxidation/esterification, and the alcohol oxidation ladder.
🧠 Section A · Concept Check ● BEGINNER 4 × 1 = 4
1-COOH is the functional group of:
2Alkenes typically undergo:
3A 3° alcohol upon attempted oxidation:
4Alkane + halogen reaction requires:
🧮 Section B · Problem Solving ● INTERMEDIATE 2 + 3×3 = 11
5A 1° alcohol oxidises first to an aldehyde, then to a .
6The ester functional group is written .
7Write the general esterification equation.
8What distinguishes an aldehyde from a ketone structurally?
9Name the product when a 2° alcohol is oxidised.
🚀 Section C · Challenge ● CHALLENGE 5
10A compound oxidises to a ketone and does not oxidise further. What class of alcohol must it be, and why can't 3° alcohols be oxidised the same way?

1-B 2-B 3-C 4-B | 5 = carboxylic acid 6 = -COO- 7 = RCOOH + ROH ⇌ RCOOR + H2O 8 = an aldehyde's C=O is on a terminal (end) carbon (-CHO), a ketone's C=O is on an internal carbon 9 = a ketone | 10 = It must be a 2° (secondary) alcohol, since only 2° alcohols oxidise to ketones and then stop; 3° alcohols have no hydrogen atom on the carbon bonded to the -OH group, and oxidation of an alcohol requires removing that hydrogen, so a 3° alcohol simply has no such hydrogen to remove and cannot be oxidised by the usual reagents.
