Answer 1

The unknown is soluble in water and gives bubbles coith 5.. NaHCO3 = carboxylic acid R-COOH + NaHCO3 -> RCOONa + CO 2 + H2O The unknown is insoluble in toateo, insoluble is 6:1. NOOH I but soluble in st. HOI = Amine | R- NH3 + HCl -> 8- NH có Golf: The unknown is soluble in cooteo , do not produce bubbleau 5.). NAHCO 3 , gives por coith 2.4-DNP of gives silver miosor test. = aldehyde R-C=O + HIN-NH-_)-NOR → R-CH= N-NH T IL NOD Noa Noa R-CHO + 2 Ag(NH3)* + 201 - R-COOH + 2 Ag+ + H2O silver miorico the unknow is in goluble in H20,51. NaOH, 53.HCI , Soluble in conc. H2504.3 Aikene R-CH=CH, H2S04, R-CH-CHI R-CH=CH2 603, RÇH-CH2 osogH so so Decolourisation of 802
