Answer:
Correct Answer: 5. $(b, d)$
Solution:
- According to the given conditions, compound (d) neither reacts with neutral ferric chloride solution nor with Fehling solution. It however reacts with Grignard reagent and gives positive iodoform test.
- As the compound does not contain any phenolic $-OH$ group. Hence, it gives negative neutral $FeCl _3$ test.
- Compound gives reaction with $R \operatorname{Mg} X$ as it contains ${ } _O^{C}-Et$
Compound with $CH _3 CH$ - group undergoes iodoform test in $OH$
presence of $NaOH$ and $I _2$.
