Hello students, so in this video we are going to react sodium acetylite with 1 -bromobutane.
00:11
So they are going to follow sn2 mechanism.
00:15
Sodium acetylite is hc triple bond c -na +, this is the nucleophile and it is going to react with 1 -bromobutane.
00:25
So let the bromine be here and this is the carbon atom and this carbon atom has 2 h attached to it and suppose this and this one has ch2, ch2, ch3.
00:41
So you can see 1, 2, 3, 4 and 4th carbon is connected to the bromine.
00:46
So these are the alpha hydrogens.
00:49
So the base is going to attack this side from the back.
00:58
So sn2, in the sn2 the base attacks from the back.
01:01
So what happens if a transition state is formed? it is a one step reaction, no carbocation is formed here...
