Explain the following reactions. (i) CH_3 - CH_2OH underset(Na_2Cr_2O

1.	Explain the following reactions. (i) CH_3 - CH_2OH underset(Na_2Cr_2O_7)overset("acidified")to?(ii) CH_3-underset(OH)underset(\|)(CH) - CH_3 underset(Na_2Cr_2O_7)overset("acidified")to ? (iii) CH_3 - CH_2 - CH_2OH overset(PC C)to ?
Answer» Solution :(i) `underset("ethanol")(CH_3-CH_2OH) underset((O))OVERSET("acidified" Na_2Cr_2O)tounderset("ethnal")(CH_3-CHO)underset((O))overset("acidified " Na_2Cr_2O_7)to underset("ethanoicacid")(CH_3-COOH)` (ii) `underset("PROPAN - 2- ol")(CH_3-underset(H)underset(\|)CH-CH_3) underset((O))overset("acidified" Na_2Cr_2O_7)to underset("Propanone")(CH_3-underset(O)underset(\|\|)C-CH_3) underset((O))overset("acidified" Na_2Cr_2O_7) to underset("ethanoic acid")(CH_3-underset(O)underset(\|\|)C-OH)` (III) `underset("Propan - 1- ol")(CH_3-CH_2 - CH_2-OH) overset(PC C)tounderset("Propanal")(CH_3 - CH_2 - CHO)`
