ऐल्डिहाइड और कीटोन कार्बनिक रसायन बोर्ड परीक्षा प्रश्न है फॉमूले और रिएक्शन को keyboard से लिखना सम्भव नही है ज्यादा स्पष्टीकरण के लिए आइ बटन पर click next प्रश्न - An organic compound "A" containing 69.77% carbon, 11.63% hydrogen, and the rest oxygen, with a molecular mass of 86, is likely 2-pentanone (C5H10O), a methyl ketone that does not reduce Tollens' reagent but forms an addition compound with sodium hydrogensulphite and gives a positive iodoform test
Solution:
%C=69.77%;%H=11.63%
∴%O=100−(69.77+11.63)=18.6%
C:H:O=1269.77:111.63=1618.6
=5.8:11.63:1.16
⇒5:10:1
∴ The E.F. of the given compound is C5H10O
E.F. mass =5×12+10×1+1×16=86
Since, mol. mass = 86 (given)
∴M.F.=C5H10O
Since the given compound on vigorous oxidation gives a mixture of ethanoic acid and propanoic acid, therefore, the methyl ketone is pentan-2-one, i.e.
What are Aldehydes and ketones? aldehydes, the carbonyl group has one hydrogen atom attached to it together with either a 2nd hydrogen atom or a hydrogen group which may be an alkyl group or one containing a benzene ring.
One can notice that all these have the exact same end to the molecule.
