Briefly explain two chemical tests which can be used to identify the formation of this compound as aldehyde or ketone.

The correct answer is :

1) Fehling's test,

2) Tollen's test

Explanation:

1. Fehling's Test is the test that confirms the presence of aldehydes by the Fehling solution that contain copper ion with tartrate ions in NaOH solution. The color of the solution is blue due to presence of copper ions. In this test aldehydes are confirmed by the reduction of the blue solution to a insoluble precipitate of copper oxide red color while in presence of ketones there is no change.

2. Tollen's test is also a test that help in identifying the presence of aldehyde as the Tollen's reagents oxidizes aldehydes where ketones as they lack hydrogen in them.

Thus, the correct answer is : 1) Fehling's test,

2) Tollen's test.
