2 fer EC Q 2. (A) An organic nitrogen heterocycles A having molecular formula C6H1N1, on catalytic reduction with Hz/Ni at high temperature and pressure gives amine 'B' (C6H13N1). Amine B on reaction with 2 moles of Mel followed by heating with AgoH selectively provides N,N- dimethylhex-5-en-1-amine (unsaturated amine C') having molecular formula C3H17N1. Further, reaction of unsaturated amine C with Mel and subsequent heating with AgOH gives hexa-1,5- diene 'D' (C6H10) and amine 'E'. Compound A on oxidative with KMnO4 gives a-picolinic acid. Identify all the products and explain the formation of compound D starting from compound B with proper mechanism. of 2 [3] Hz/Ni i. 2 Mel A C6H7N i Mel 150 C Pressure [B] C H 3N ii.
