WebThe correct order of decreasing Lewis acid character amongst the given halides is: 1. AlCl3 2. BCl3 3. GaCl3 4. InCl3 This is because the Lewis acid character of a compound is related to its ability to accept electron pairs. In general, compounds with smaller atomic radii and higher positive charges have greater Lewis acid character.
WebAnswer (1 of 5): Original Question:- Which of the species BF3 and AlCl3 is more acidic, both are electron deficient. Answer:- In case of BF3 one can argue that there is extensive p-π-p-π back bonding and as a result the electron deficiency is less. That means that the positive charge on the o...
