Assertion (A): Ethyl Alcohol vapour is passed over anhydrous alumina as catalyst at

350^\circ C

acetaldehyde is obtained.
Reason (R): Emulsions contain liquid dispersed in liquid.

View answer and explanation

Correct option: D

(A) is false but (R) is true

Option D ((A) is false but (R) is true) is correct because the oxidation of ethyl alcohol to acetaldehyde requires a catalyst like copper at 573K, not alumina at 350°C, and emulsions are indeed liquid dispersed in liquid.
