 So let's do this problem Which would be more polar of a bond when bonded to I don't know Sulfur or oxygen Okay, so what do we do we think about the sulfur phosphorous bond? Or the oxygen phosphorous bond? Then we look up the electronegativities of these three elements So this is 2.1 and in fact, this is device Sulphur is 2.5 And oxygen is 3.5 So how do I figure this out? I say minus minus So 2.5 minus 2.1 is 0.4 Device and this is 3.5 minus 2.1. So that's 1.4 device So which one of these is the more polar ball oxygen phosphorous ball? Okay, why? because 1.4 is bigger than And do we need to record another one guys good
