This is achieved by adding very dilute ammonia solution drop by drop while shaking the solution. It is called neutral because the pH value should be maintained at 7. The test used to detect carboxylic acid is called neutral FeClX3 F e C l X 3 test. Compound gives positive iodoform test Web31. Hence carbonyl compound A having molecular formula C 5 H 10 O is pentan. Pentan – 2 – one gives positive iodoform test, but it does not reduce Fehling’s solution.
