Answer:
p-fluoronitrobenzene and sodium phenoxide is more appropriate
Explanation:
An ipso substitution is required to form p-nitrophenyl phenyl ether.
For this ipso substitution, an alkoxide anion needs to attack as a nucleophile at the carbon atom attached to fluorine atom and thereby substitute that F atom.
p-nitrophenoxide is an weak nucleophile as compared to phenoxide due to presence of electron withdrawing resonating effect of nitro group at para position.
p-fluoronitrobenzene is a good choice for nucleophilic attack by alkoxide anion as compared to fluorobenzene due to higher positive charge density at carbon atom directly attached to F atom. Higher positive charge density arises due to presence of electron withdrawing resonating effect og nitro group at para position.
So, p-fluoronitrobenzene and sodium phenoxide is more appropriate
<u>Answer:</u> The vapor pressure of solution is 459.17 mmHg
<u>Explanation:</u>
To calculate the number of moles, we use the equation:
.....(1)
- <u>For testosterone:</u>
Given mass of testosterone = 7.752 g
Molar mass of testosterone = 288.4 g/mol
Putting values in equation 1, we get:
- <u>For diethyl ether:</u>
Given mass of diethyl ether = 208.0 g
Molar mass of diethyl ether = 74.12 g/mol
Putting values in equation 1, we get:
Mole fraction of a substance is calculated by using the equation:
The formula for relative lowering of vapor pressure will be:
where,
= vapor pressure of solvent (diethyl ether) = 463.57 mmHg
= vapor pressure of the solution = ?
i = Van't Hoff factor = 1 (for non electrolytes)
= mole fraction of solute (testosterone) = 0.0095
Putting values in above equation, we get:
Hence, the vapor pressure of solution is 459.17 mmHg
