Answer 1

Layer’s Test is a chemical test used to detect the presence of aldehydes. In this test, the aldehyde is treated with ammoniacal silver nitrate solution. If the compound contains an aldehyde group, a silver mirror will form on the inner walls of the test tube due to the reduction of silver ions to metallic silver.
