True or false (encircle as appropriate). 1. 5% NaHCO3 solution differentiates between a carboxylic acid and an alcohol. True / false 2. Beilstein flame test is meant to determine whether the compound is aromatic. True / False 3. Lucas reagent is a mixture of zinc chloride and hydrochloric acid True / False 4. Black soot is obtained when you burn a non-aromatic compound in open flame. True / False 5. Esters react with hydroxylamine hydrochloride under basic conditions. True False

Answer 1

1. 5%. NaHCO3 solution differentiates between a ca acid and an alchol - Tone. becaux, 57. NaHCO3 only react with Carbosodic and to give CO2 eltervescence but it doennot reacts with alchal R-COOH + NaHCO3 REOONa+ CO2 + H₂O 2. Beilstein Home test is meant to determine weather the compound is arometic False. Because it is a chemical test for organic helider. So, arometic and non-asometic both type halides response in this text 3. Lucan reagent is a mixture of Zine chloride and hydrochloric acid True. The mäxture of Enela/ucl called Lucer reagent and it is used to determine the class of alcholas. 4. Black-soot is obtained when you burn anon arometic compound in open flame a False. Black sist is abtonded from the aromelic compounds due to unburnt Carben particles h. Ester reacts with hydroxylamin bedrochloride in der basic condition - Towe As to conduct this recation 6N NOH needed.
