The following alkanols will yield alkanoic acids on reacting with excess acidified K2Cr2O7 except
CH3CH2OH
(CH3)2CHCH2OH
(CH3)3CCH2OH
(CH3)3COH
CH3CH2CH2CH2OH
Explicaţie
option D is a tertiary alkanol. tertiary alkanols are resistant to oxidation so cannot react with excess acidified \(K_2Cr_2O_7\) to give any product.
