Answer:
Introduction:
The synthesis of 2-phenyl-2-pentanol requires starting materials that can provide the necessary functional groups and carbon skeleton for the desired product. In this case, we need a compound that can provide a phenyl group (C6H5) and a pentyl group (CH3CH2CH2CH2) connected by an alcohol functional group (-OH). Let's analyze each option to determine which one can be used as a starting material in the synthesis of 2-phenyl-2-pentanol.
Options Analysis:
a) CH3(CH2)2CH2Br and C6H5COOH:
- CH3(CH2)2CH2Br: This compound does not contain a phenyl group or a pentyl group, so it cannot be used as a starting material for the synthesis of 2-phenyl-2-pentanol.
- C6H5COOH: This compound contains a phenyl group, but it does not contain a pentyl group. It is an acid (carboxylic acid), which is not suitable for the synthesis of 2-phenyl-2-pentanol.
b) (CH3)2CHCH2Br and PhCOCH3:
- (CH3)2CHCH2Br: This compound does not contain a phenyl group but contains a pentyl group. However, it lacks the hydroxyl (-OH) functional group required for the synthesis of 2-phenyl-2-pentanol.
- PhCOCH3: This compound contains a phenyl group but does not contain a pentyl group. It also lacks the hydroxyl (-OH) functional group required for the synthesis of 2-phenyl-2-pentanol.
c) PhBr and CH3CH2CH2COCH3:
- PhBr: This compound contains a phenyl group, which is one of the required functional groups for the synthesis of 2-phenyl-2-pentanol.
- CH3CH2CH2COCH3: This compound contains a pentyl group and a carbonyl functional group (C=O). The carbonyl group can be converted to an alcohol (-OH) group through reduction, which is suitable for the synthesis of 2-phenyl-2-pentanol.
d) PhBr and (CH3)2CHCH2COCH3:
- PhBr: This compound contains a phenyl group, which is one of the required functional groups for the synthesis of 2-phenyl-2-pentanol.
- (CH3)2CHCH2COCH3: This compound does not contain a pentyl group but contains a carbonyl functional group (C=O). Similar to option (c), the carbonyl group can be converted to an alcohol (-OH) group through reduction, which is suitable for the synthesis of 2-phenyl-2-pentanol.
Conclusion:
Among the given options, only option (c) - PhBr and CH3CH2CH2COCH3 - provides both the phenyl group and the pentyl group required for the synthesis of 2-phenyl-2-pentanol. Therefore, option (c) is the correct choice for the
