1. Major product in photobromination of 2 methyl butane is _____

abb0t · Answer

This is similar to what we went over last time, this is a radical reaction. Formation of more stable product. |dw:1396882725530:dw|

aravindg · Answer

So 3 degree carbon gets bromine here.

aravindg · Answer

2 BROMO 2 METHYLBUTANE right?

abb0t · Answer

oh wait, you do. Lol Soryr.

aravindg · Answer

Yeah lol so 2 BROMO 2 METHYLBUTANE right?

aravindg · Answer

How about the product of treating ethyl benzene and n bromo succinimide?

aravindg · Answer

@abb0t

abb0t · Answer

brominate the alkane, not the benzene.

aravindg · Answer

So n bromo succinimde is a brominating reagent?

abb0t · Answer

yes. another radical reaction. is it just NBS or is there another agent in solution? like CCl$_4$ or something?

aravindg · Answer

Just NBS

How about this qn:
Identify the order of basicity:

abb0t · Answer

Well, look at their conjugate structures and then draw out their resonance strcutrues.

aravindg · Answer

Does the N atom of 2nd compound get involved in resonance?

abb0t · Answer

Yes. It can partake in resonance.

aravindg · Answer

I have a doubt in that.

aravindg · Answer

And what factor should we use to differentiate 1 and 3?

abb0t · Answer

Remember, resonance is simply delocalization of electron density. This gives the molecle a stabilizing effect, since it can be distributed in a greater area.

abb0t · Answer

One has an oxygen, while the other has a carbon.

aravindg · Answer

ofc I see that lol..I asked the factor :P
