Hydrocarbons 2 Question 44
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 $-\mathrm{COCH}_{3}$ or
$-\mathrm{CH}(\mathrm{OH})$ 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 $\mathrm{CH}_{3} \mathrm{CO}$ group as Indicated. Hence, correct choice is (c).
