 let's try this one it says from left to right what is the hybridization of the carbon atoms in the compounds below so left to right um can anybody tell me the hybridization of this compound or this carbon sp right okay very good uh what's the bond angle there if it's sp 180 it's 180 yeah you got it good job okay what about this one over here sp2 right okay what's the bond angle there 120 degrees yes very good always right and this one sp3 very good and what's the bond angle there okay um how about this can i yeah what's your question um i never realized why we didn't like count the oh this oxygen here uh because it wasn't indicated because yeah it just said these three particular ones oh but if we wanted to do that one yeah we wanted to do that one um for this carbon atoms yeah it's the carbon those particular carbon atoms yeah if we wanted to do we can do that oxygen the one thing about this structure and a lot of these structures that they give you on the paper is the other um lone pairs aren't being shown okay so it's sometimes difficult to figure out what the hybridization of those things are if the lone pair isn't shown and you don't know that you have to fill that up 10 okay so how many lone pairs are on that oxygen two lone pairs right so it looks like that right so there's three electron groups so what's the hybridization of that oxygen sp2 very good yeah so that one's sp2 okay and we can't talk about a bond angle because they're in the wall okay so that's a good one everybody did very well and that was a really good question actually i thought so any other questions before we kill this one okay very good huh you were going to ask us something else oh i think it was something to do with uh one of the uh heteroatoms that didn't have any lone pair electrons on it okay any other questions wonderful
