A) Hydrogenation
B) lodoform 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. \[\underset{2\,\text{butanol}}{\mathop{C{{H}_{3}}-C{{H}_{2}}-\overset{OH}{\mathop{\overset{|}{\mathop{C}}\,}}\,H-C{{H}_{3}}}}\,\] \[C{{H}_{3}}-\underset{1-\text{propanaol}}{\mathop{C{{H}_{2}}-\underset{H}{\overset{H}{\mathop{\underset{|}{\overset{|}{\mathop{C}}}\,}}}\,-OH}}\,\]Test | 2-butanol | 1-propanol | |
[a] | lodoform test | Yellow ppt. | No change |
[b] | Lucas test | Turbidity 5-10 min | No change |
[c] | Oxidation test | Ketone formed | Aldehyde formed |
