Q1. A student attempts to purify a mixture of organic compounds using saturated sodium bisulfite. Which pair of compounds will both form white crystalline precipitates?
Answer: Propanone and Ethanal
Explanation: Sodium bisulfite forms white crystalline adducts with all aldehydes and methyl ketones. Option B fails because 3-pentanone is not a methyl ketone.
