Chiral Alcohol and Hydrogenation
To understand why option A is the correct answer, let's analyze the given information step by step.
1. Hydrogenation of Chiral Alcohol
The original chiral alcohol, C5H10O, is subjected to catalytic hydrogenation, which involves the addition of hydrogen gas (H2) under the presence of a catalyst (usually a metal catalyst like platinum, palladium, or nickel). This process reduces the double bond in the alcohol molecule and converts it into an achiral alcohol, C5H12O.
2. Achiral Carbonyl Compound
The original chiral alcohol is oxidized by activated MnO2 to form an achiral carbonyl compound, C5H8O. This oxidation process converts the alcohol functional group (-OH) into a carbonyl group (C=O), resulting in the loss of chirality.
3. Determining the Chiral Alcohol
Now, let's analyze the given options and determine which one could be the chiral alcohol.
a) 1-penten-3-ol
This alcohol has a double bond in the pentene chain, which means it can undergo hydrogenation to form an achiral alcohol. Therefore, it cannot be the chiral alcohol.
b) 4-penten-2-ol
Similar to option A, this alcohol also has a double bond in the pentene chain. Thus, it can also undergo hydrogenation to form an achiral alcohol. Hence, it cannot be the chiral alcohol.
c) 3-methyl-2-buten-1-ol
This alcohol has a double bond in the butene chain, which can be hydrogenated to form an achiral alcohol. Therefore, it cannot be the chiral alcohol.
d) 2-methyl-2-buten-1-ol
This alcohol has a double bond in the butene chain, which can be hydrogenated to form an achiral alcohol. Hence, it cannot be the chiral alcohol.
Conclusion
Among the given options, only option A (1-penten-3-ol) cannot form an achiral alcohol upon hydrogenation. Therefore, option A is the chiral alcohol in this case.
