hi all! I am not able to understand what's a Lewis acid and a Lewis base. tell me if these are Lewis acids or Lewis bases and tell me the reason. HCl, H2SO4, H3PO4, CO2, HCN.
my approach: first 3 I'm not able to decide. 4th one I thought to be Lewis base as 2lone pairs of electrons left in each oxygen atom. but I found somewhere written that it's an acid. 5th one is base as 1pair of electrons left in nitrogen atom. please help. also tell me the criteria to check if a compound is electron deficient or has excess electrons. also how to find the central atom.
