can someone clarify the diff once for me?
can someone clarify the diff once for me?
Lemme guess, those kaplan orgo subject tests confused you too? They ask about melting point and the explanation is about boiling point, and vice versa lol. I guess they have some similarities but I would also like a breakdown!
I dunno. I think Kaplan is right on that one... it makes sense logically to say that if the molecules have less branching, they can pack together tightly.
If they have branching, they won't pack as tightly, and they will break apart easier.....
hmm.
melting point:
symmetry means everything, i.e. trans alkene, because of the symmetrical shape, it can pack tighter, lead to high m.p. cause you need to have more energy to break the intermolecular force.
boiling point:
look for polarity, i.e. cis alkene is more polar than trans (I wish I could draw it out, it's kinda hard to explain...) thus it has higher b.p.
