Ethanol is a primary alcohol whereas propan-2-ol is a secondary alcohol
And secondary alcohol gives Iodoform test whereas Primary alcohol does not give this test.
Here, is the explanation of the Iodoform test given by propan-2-ol:-
Addition of I2(aq) (usually I2 dissolved in KI, shown here reacting with 2-propanol
2 NaOH + I2 + CH3CH(OH)CH3 → 2 NaI + CH3COCH3 + 2 H2O
oxidizes the hydroxyl group to a ketone,
The ketone formed reacts with the I2(aq) in a substitution reaction to produce a triiodoketone, for example triiodoacetone.
CH3COCH3 + 3I2 → CH3COCI3 + 3HI
