1C6H62 or glycerol, CH21OH2CH1OH2CH2OH,

Accepted Answer

Hi everyone for this problem we are asked to identify the compound that would be more soluble in octane from the following pair ethylene, glycol or tall you line. So for soluble itty recall that like dissolves like which means compounds with the same polarity and inter molecular force can dissolve each other. So let's take a look at our octane. Okay, so for octane we have carbons and hydrogen. So this is an example of a hydrocarbon. And hydrocarbons are non polar compounds. So this means that our octane is a non polar molecule that exhibits dispersion forces. So let's take a look at our ethylene glycol and our towline. So I'll just rewrite that here. Okay, so for ethylene glycol, since hydrogen is bonded directly to oxygen which is an electro negative atom, we can say that this is a polar compound that exhibits hydrogen bonding for our towline. This is an example of a hydrocarbon. This means it's a non polar molecule that exhibits dispersion forces. So out of the two are told is going to be more soluble in octane because they are the most similar. Okay, that's the end of this problem. I hope this was helpful
