A) Hydrogenation
B) Iodoform test
C) Lucas test
D) Oxidation test
Correct Answer: A
Solution :
Key Idea: The test in which the substances which are to be distinguished give different coloured solution\[/ppt\] or smell are useful in distinguishing substances. \[\underset{\text{2butanol}}{\mathop{C{{H}_{3}}-C{{H}_{2}}-\overset{\begin{smallmatrix} OH \\ | \end{smallmatrix}}{\mathop{C}}\,H-C{{H}_{3}}}}\,\] \[\underset{1-propanol}{\mathop{C{{H}_{3}}-C{{H}_{2}}-\underset{\begin{smallmatrix} | \\ H \end{smallmatrix}}{\overset{\begin{smallmatrix} H \\ | \end{smallmatrix}}{\mathop{C}}}\,-OH}}\,\]Test | 2-butanol | 1-propanol | |
[a] | Iodoform test | Yellow\[ppt\] | No change |
[b] | Lucas test | Turbidity\[5-10\min \] | No change |
[c] | Oxidation test | Ketone | Aldehyde formed |
