List the following compounds in decreasing electronegativity difference. Br2 HBr KBr
Generally Electronegativity difference is more between different atoms and that to metal and non metal it is more pronounced.
H-2.2, K-0.8 and Br-2.96
So KBr(2.16)> HBr(0.76)>Br2(0)

How many grams of Br2 is required to produce 6.80 moles of KBr given the following equation: 2K + Br2 -> 2KBr
Three of the compounds have ionic bonds (difference in electronegativity is greater or equal to 2, or between 2 and 1.6 if it is metal + non-metal). Which? AlBr3 SeS2 HgCl2 CaCl2 PbCl2 NaBr Li2O SiO2 I thought it was CaCl2, NaBr, PbCl2 and Li2O from what I managed to learn online. But thats four not three, what am I doing wrong?
