Lucas Test Simulator

Lucas Test for Alcohols

Differentiate 1°, 2°, and 3° alcohols based on substitution kinetics.

1. Setup Experiment

Select Unknown Alcohol

1-Butanol (Primary 1°) 2-Butanol (Secondary 2°) t-Butyl Alcohol (Tertiary 3°)

2. Observation

00:00

Solution State Clear

Status: Standby. Select an alcohol and add the Lucas reagent. Watch the physical state of the solution over time.

3. Mechanism (S_N1)

The Lucas test relies on the formation of a carbocation intermediate.

Speed depends on stability:
3° Carbocation: Highly stable (Fast)
2° Carbocation: Moderately stable (Slow)
1° Carbocation: Unstable (No Reaction at RT)
