Answer:
Benzoyl Chloride
Explanation:
Friedel-Craft Acylation is reaction utilized to add electrophiles (particularly carbonyl group) across double bonds of aromatic compounds.
In given case benzophenone is synthesized using benzene and benzoyl chloride.
Mechanism:
Step 1: In first step benzoyl chloride is treated with lewis acid to generate an electrophile i.e. oxo(phenyl)methylium.
Step 2: In the second step benzene undergoes electrophilic substitution reaction and adds the electrophile.
Step 3: In last step the aromaticity of benzene is restored with the elimination of proton.
Answer:
Explanation:
The expression for Clausius-Clapeyron Equation is shown below as:
Where,
P is the vapor pressure
ΔHvap is the Enthalpy of Vaporization
R is the gas constant (8.314×10⁻³ kJ /mol K)
c is the constant.
For two situations and phases, the equation becomes:
Given:
= 13.95 torr
= 144.78 torr
= 25°C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T = (25 + 273.15) K = 298.15 K
= 298.15 K
= 75°C = 348.15 K
So,
