Video transcript

Hello everyone today. We are being asked to identify if the compounds below. We have one compound here in one compound here will form a homogeneous solution and if so, identify the greatest inter molecular force involved. First we want to decide what two compounds we're dealing with. So right here we have CH three C. O. H. We do know that we have an O. H. Group in there and with O. H. Groups we know that that deals with hydrogen bonding. We're gonna write that just blow it hydrogen bonding for that compound there. And for the second compound, we also note that we have an O. H. Group together and that is going to also form a hydrogen bond right there. And so we know that when determining if something is homogeneous or not, it's either polar or non polar. And since we have two hydrogen bonds, we're going to say that this is polar and polar directly links to a solution or this particular solution being homogenous with the greatest inter molecular force being hydrogen bonding present between these two compounds. So we're going to see that these compounds would form a homogeneous solution through hydrogen bonding. And with that we have our answers. I hope this helped. And until next time
