Vont hoff favtor of alcl3 is 1 because 
Because alcl3 is covalent molecule. So n=1
So by i=1+a(n-1)
Vont hoff factor is1

DEAR JHEEL
For ions with a one to one ratio, like NaCl, this dissociates into ions of 
Na+1 and Cl-1 and the van't Hoff factor is then 2. 
in the same way , alcl3 will dissociate into al^+3 and 3cl- , so, total n = 4 
i = 1+1 (4-1) 
i = 4 
HOPE IT CLEARS NOW
