Question

name the reagent used in :
(i). oxidation of primary alcohol to aldehyde.
(ii). dehydration of propan-2-ol to propane.
(iii). butan-2-one to butan-2-ol​

Answer 1

Answer:

(I) pyridine chloro chromate

(ii) Propan-2-ol can be dehydrated to give propene by heating it with an excess of concentrated sulphuric acid at about 170°C. Concentrated phosphoric(V) acid, H3PO4, can be used instead. The acids aren't written into the equation because they serve as catalysts

(iii) aluminium hydride and sodium borohydride can be used to convert butan-2-one to butan-2-ol.
