Column I | Column II |
(A) Acetaldehyde, Vinyl alcohol (B) Eclipsed and staggered ethane (C) (+) 2-butanol, (-) 2- butanol (D) Methyl-n- propylamine and diethylamine | 1. Enantiomers 2. Tautomers 3. Chain isomers 4. Conformational isomers 5. Metamers |
A) A B C D 1 4 3 5
B) 2 4 1 5
C) 5 1 4 2
D) 5 1 3 2
Correct Answer: B
Solution :
\[\underset{\text{acetaldehyde}}{\mathop{\text{C}{{\text{H}}_{\text{3}}}\text{CHO}}}\,\xrightarrow{\text{Tautomerisation}}\underset{\text{Vinyl alcohol}}{\mathop{\text{C}{{\text{H}}_{\text{2}}}\text{=CH-OH}}}\,\] Thus, these two are tautomers. Eclipsed and staggered ethane are two conformations of ethane. (+) 2-butanol and (-)2-butanol are enantiomers as these are non-superimposable mirror imagesYou need to login to perform this action.
