DIRECTIONS SUMMARISED D. 2.3 only are correct are correct is correct 3 only 1.2.3 are 1,2 only correct 71. Oxalic acid (ethariedioic acid) 1. canniot be oxidised by potassium permanganate (VII) 2 is the simplest aliphatic dicarboxylic acid is urod in volumetric analysis 3. 72. Aliphatic carboxyic acids can be prepared by the oxidation of tertsary alcohols using 1. an acidified manganate (VI) solution 2 hydrolysing acid anhydrides 3. the oxidation of methylketones in the haloform reaction 73. Methanoic acid 1. can be dehydrated by conc.sulphunic acid to give carbon monoxide 2. gives a black precipilate on warming with Tollen's reagent 3. gives a reddish precipitate on warining with Fehling's solution 74 Ethanoic acid is a 1. weaker acid than benzoic acid 2. weaker acid than chloroethanoic acid 3. stronger acid than propenoic acid
