Concept introduction
Vant’t Hoff factor is derived from osmotic pressure. Osmotic pressure is the pressure that is needed to stop osmosis. Osmotic pressure of the solution is directly proportional to the concentration of the solution. We can calculate osmotic pressure by using this formula is given by,
Osmotic pressure
(π) = iMRT
Where,
i- Von’t Hoff’s factor
M – Molarity of the solution (mol/L)
R- Ideal gas constant (0.08206
L atm mol-1K-1)
T-Temperature in Kelvin
Van’t Hoff factor is the ratio between actual colligative property of the particle and expected colligative property of the particle.
Draw the major substitution products you would expect for the reaction shown below. If substitution would not occur at a significant
rate under these conditions, check the box underneath the drawing area instead.
Be sure you use wedge and dash bonds where necessary, for example to distinguish between major products.
Note for advanced students: you can assume that the reaction mixture is heated mildly, somewhat above room temperature, but
strong heat or reflux is not used.
