How many isomers are possible for C2H6O:
Correct answer: C. 8
- A. 2
- B. 4
- C. 8
- D. 5
Explanation
For the chemical formula C2H6O, which represents an alcohol (ethanol), there are 8 isomeric structures possible. These isomers can be classified as follows:1. Ethanol (CH3CH2OH) - Primary alcohol2. Dimethyl ether (CH3OCH3) - Ether3. Methyl ethyl ether (CH3OCH2CH3) - Ether4. Ethyl methyl ether (CH3CH2OCH3) - Ether5. Ethylene oxide (C2H4O) - Oxirane6. Acetaldehyde (CH3CHO) - Aldehyde7. Methoxyethane (CH3OCH2CH3) - Ether8. Acetone (CH3COCH3) - Ketone Therefore, option c is correct.

About Isomerism
Isomerism occurs when compounds have the same molecular formula but different atom arrangements or spatial orientations. The content includes chain, position, functional, metameric and tautomeric isomerism, along with geometrical and optical isomerism, including cis-trans forms, E/Z notation, chirality and enantiomers.
