Question
896 mL vapour of a hydrocarbon 'P' having carbon 87.80% and hydrogen 12.19% weighs 3.28 g at STP. Hydrogenation of 'P' gives 2-methyl pentane. Also 'P' on hydration in the presence of H2SO4 / HgSO4 gives a ketone 'Q' having molecular formula C6H12O. The ketone 'Q' gives a positive iodoform test. The INCORRECT statement is:
💡 Solution & Explanation
C H3 CH CH3 CH2 C CH (P) 2 2H g C H3 CH CH3 CH2 CH2 CH3 2-methyl pentane 2 4 4 H SO HgSO C H3 CH CH3 CH2 C CH3 O (Q) The ketone (Q) gives positive Iodoform test and shows 2,4-DNP test. It also forms white crystalline product with NaHSO3.
