Match the compounds in LIST- I with the observations in LIST- II , and choose the correct option. LIST- I LIST- II I Aniline P Sodium fusion extract of the compound on boiling with FeSO 4 , followed by acidification with conc. H 2 SO 4 , gives Prussian blue color. II o - Cresol Q Sodium fusion extract of the compound on treatment with sodium nitroprusside gives blood red color. III Cysteine R Addition of the compound
Options
- AI → P , Q ; II → S ; III → Q , R ; IV → P
- BI → P ; II → R , S ; III → R ; IV → Q , S
- CI → Q , S ; II → P , T ; III → P ; IV → S
- DI → P , S ; II → T ; III → Q , R ; IV → P
Correct answer
D. I → P , S ; II → T ; III → Q , R ; IV → P
Step-by-step solution
I Since it contains both carbon and nitrogen so its sodium fusion extract with boiling FeSO 4 , followed by acidification with conc. H 2 SO 4 gives Prussian blue colour. Fe 2 + + 6 CN - → Fe CN 6 4 - 3 Fe CN 6 - 4 + 4 Fe 3 + → xH 2 O Fe 4 Fe CN 6 3 . xH 2 O Prussian blue I - P , S II o - Cresol Violet coloured complex III Cysteine Since it has both, sulphur and nitrogen, so its sodium fusion extract will give blood red colour with Fe 3 + and it has carboxylic group so it will give effervescence with NaHCO 3 .
