Question

A. If your unknown was 3-methylcyclohexene, what would you expect the results of the following tests to be?

1. Jones Oxidation Test:

2. 2,4-DNP Test:

3. Flame Test:

4.Beilstein Test:

B. What is 3-methylcyclohexene solubility in:

1. H20

2. NaOH

3. NaHCO3

4. HCL

5. H2SO4

Answer 1

Jones oxidation test: negative

explanation: jones oxidation test will help to find the hydroxy group but there is no hydroxy group in 3-methylcyclohexene

2,4-DNP test: negative

explanation: DNP test will help to find the carbonyl group of aldehyde or ketone but there is no carbonyl group in 3-methylcyclohexene

Flame test: it will produce sooty flame

Beilstein test: negative

Beilstein test is helpful to identify the halide group present in molecule but there is no halide group in 3-methylcyclohexene

B.

solubility test

3-methylcyclohexene is non-polar organic compound therefore insoluble in

H2O, HCl, NaOH, NaHCO3

soluble in concentrated H2SO4 ( it will react with alkene)
