|---|---|
(P)
| (1) Product is water soluble. |
(Q)
| (2) Product forms a yellow precipitate with I₂ + OH⁻. |
(R)
| (3) Product gives red colour in Victor-Mayer test. |
(S)
| (4) Product gives blue colour in Victor-Mayer test. |
| (5) Boiling point of product is higher than ethanol. |
Options:
Answer:
B
Solution:
Grignard products after work-up: P ethanol, Q isopropanol, R tert-butanol, S isobutanol. All have water solubility (not necessarily miscibility). P/Q give iodoform. Primary P/S give Victor-Meyer red, secondary Q blue. Q/R/S boil above ethanol; P does not. All listed matches follow. Correct matching option: B.
