Which compounds among the following give positive iodoform test?
Options
- A(i), (iii) and (vi)
- B(iii), (iv) and (v)
- C(i), (ii) and (v)
- D(ii), (iv) and (vi)
Correct answer
C. (i), (ii) and (v)
Step-by-step solution
A positive iodoform test is given by compounds having CH ₃ CO group in their structure. When iodine and sodium hydroxide are added to a compound that contains CH ₃ CO group in -position, a pale yellow precipitate of iodoform is formed. So, compounds (i), (ii) and (v) have CH ₃ CO group. Hence, they will give positive iodoform test.
