Answer:
Option C
Explanation:
(a) CH3CH2CH2OHalk.KMnO4→orK2Cr2O7/H+CH3CH2CHO
→CH3CH2COOHFehlingsol.→NoReaction
(b) CH3CHOHCH3alk.KMnO4→orK2Cr2O7/H+CH3COCH3
→CH3COOHFehlingsol.→NoReaction
(c) CH3CH2CH2OHCu→CH3CH2CHOFehlingsol.→Cu2O(Red)
CH3CHOHCH3Cu→CH3COCH3Fehlingsol.→Noreaction
(d) CH3CH2CH2OH OR
CH3CHOHCH3Conc.H2SO4→CH3CH=CH2
