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

Direction: Read the passage given below and answer the following questions:In spite of the predictions of stable noble gas compounds since at least 1902, unsuccessful attempts at their synthesis gave rise to the widely held opinion that noble gases are not only noble but also inert. It was not until 1962 that this dogma was shattered when Bartlett in Canada published the first stable noble gas compound XePtF6. This discovery triggered a worldwide frenzy in this area, and within a short time span many new xenon, radon, and krypton compounds were prepared and characterized. The recent discoveries show the ability of xenon to act as a ligand . The discovery by Seppelt’s group that more than one xenon atom can attach itself to a metal center which in the case of gold leads to surprisingly stable Au- Xe bonds. The bonding in [AuXe4]2+ involves 4 Xe ligands attached by relatively strong bonds to a single Au(II) center in a square planar arrangement with a Xe-Au bond length of about 274 pm This discovery provides not only the first example of multiple xenon ligands but also represents the first strong metal - xenon bond.Q.Compounds of noble gases except _______ are known.
