Answer:
See explanation
Explanation:
This conversion must go through a sequence of steps as i have shown in the image attached to this answer.
The acetone is converted to propan-2-ol using LiAlH4, THF and acid. The propan-2-ol may be converted to propene by E2 elimination. Addition of HBr yields 2-bromo propane.
The Wurtz reaction converts 2-bromo propane to 2,3- dimethyl butane. This can be brominated in the presence of light to yield 3-bromo-2,3-dimethyl butane. Elimination of HBr using a base leads to the formation of the required product as shown.
Answer : The volume of will be, 514.11 ml
Explanation :
The balanced chemical reaction will be,
First we have to calculate the mass of in tablet.
Now we have to calculate the moles of .
Molar mass of = 1 + 12 + 3(16) = 61 g/mole
Now we have to calculate the moles of .
From the balanced chemical reaction, we conclude that
As, 1 mole of react to give 1 mole of
So, 0.0202 mole of react to give 0.0202 mole of
The moles of = 0.0202 mole
Now we have to calculate the volume of by using ideal gas equation.
where,
P = pressure of gas = 1.00 atm
V = volume of gas = ?
T = temperature of gas =
n = number of moles of gas = 0.0202 mole
R = gas constant = 0.0821 L.atm/mole.K
Now put all the given values in the ideal gas equation, we get :
Therefore, the volume of will be, 514.11 ml
