A) A-1 B-4 C-3 D-5
B) A-2 B-4 C-1 D-5
C) A-5 B-1 C-4 D-2
D) A-5 B-1 C-3 D-2
Correct Answer: B
Solution :
\[\underset{acetaldehyde}{\mathop{C{{H}_{3}}CHO}}\,\xrightarrow{Tautomerisation}\underset{vinyl\text{ }alcohol}{\mathop{C{{H}_{2}}=CH-OH}}\,\] Thus, these two are tautomers. Eclipsed and staggered ethane are two conformations of ethane. (+) 2-butanol and (-)2-butano are enantiomers as these are non-superimposable mirror images.You need to login to perform this action.
