Hydrocarbons - Result Question 61
####46. The correct statement with respect to product $Y$ is
(a) it gives a positive Tollen’s test and is a functional isomer of $X$
(b) it gives a positive Tollen’s test and is a geometrical isomer of $X$
(c) it gives a positive iodoform test and is a functional isomer of $X$
(d) it gives a positive iodoform test and is a geometrical isomer of $X$
Show Answer
Answer:
Correct Answer: 46. (b)
Solution:
- PLAN This problem can be solved by using the concept of iodoform test and functional isomerism.
Iodoform test The compound containing $-COCH _3$ or
$-CH(OH)$ group will undergo iodoform test
- Thus, $X$ and $Y$ are functional isomers of each other and $Y$ gives iodoform test due to the presence of $CH _3 CO$ group as Indicated. Hence, correct choice is (c).
