Lewis acids---Solubility
« on: January 08, 2011, 12:20:08 PM »
I need some help with these questions please....
1)Why does SnCl4 act as a lewis acid while CCl4 doesn't?
2) CH3OH is a lewis base or a lewis acid? O has a lone pair of electrons but on the same time the convalent bond OH is polar so there is an electron drift towards O which makes H acidic
3) Why N2 is less soluble in water than O2?What makes a non polar gas more or less soluble than an other non polar gas?
4) When BH3 dissolves in HF it acts like a base or an acid?

1. Hint : There is a certain trend that is followed in the p-block elements as you move down the group... This effect is more pronounced with the heavier elelments of the group... Try figuring out what that effect is

2. You are confusing Lewis acidity/basicity with Bronsted-Lowry acidity/basicity.The question asks you whether CH3OH is a Lewis acid/base... Think only in terms of electron pairs.

4. Hints : Central atom, octet
