Hello i am a student in the Uk doing chemistry advanced level at what you americans call college. Se is in group 6, therefore 6-2 = 4 lone pairs of electrons. So i knew it would be bent linear (<109.5) so ermm,,, i'm very suprised such a basic question got only 31% people getting it right.
Reallllllly? This was a clicker question at the beginning of class, not a quiz or exam question. Clicker questions are used for attendance. Sometimes people don't pay attention to it and they just click something so they're marked as being there. Why waste your time being irritating when this lecture is posted here for your benefit?
Why wouldn't I reply? It's not like I was watching the video 100% of the time. I had 51 minutes to find your stupid comment and fight the urge to reply. :-)
A question for someone at MIT: what are the differences between 5.111 and 5.112? Both courses cover the same material, but 5.111 seems to be more mathematics base?
@hunterbender 5.112 is supposed to be harder material; its designed for people with more chemistry and math experience. It goes into the same concepts, but with a lot more detail
In the case of Be2, How do we know that sigma2* has a lower energy than pi2. That is, how do we know that the 2pi orbital does not fill up before the 2 sigma* orbital thus making the molecule stable?
I want this video on my Optimus Chic E720 unit.

Just a slight mistake at 27:38
You put Helium squared, opposed to making the " 2 " a subscript

@EmeraldSky33 you replied to a year old comment. I am actually speechless, how obsessive do you have to be.

Awesome video, it made a lot more sense then what my prof was teaching.
Shame that MIT doesn't split it's videos into topics and provide slides to accompany this lecture.
