Explanation

Bromine water test is used to dentify the alkene or alkane functional gp. Present in the compound. These are distinguished by iodoform & lucas Test. Iodoform test is used to check the Presence of Carbonyl compound with structure 3 ||O R C CH or alcohols with 3 |OH R CH CH . Lucas test is used to distiniguish 1°, 2° & 3° alcohol on the basic of turbidity. (c) 3 || || O O H C OH &CH C OH Formic acid gives tollen's test where as acetic acid do not give tollen's test. (d) Here Tollen's test is also used to test for terminal alkynes. Ammoniacal Cu₂Cl₂ test: - Copper Salt ppt Red
