In the first part of the question we have to tell that why does the 3 -bromobutene undergo solvulises in methanol faster than 2 -bromutane? and in the second part of the question we have to tell that we have to tell that we have to tell the name of the alkyl halide that can undergo solvolysis in methanol, bromomethane or three -bromo one cyclohexane.
01:31
Now coming on to the solution.
01:34
So basically the solvolysis process or solvolysis reaction, it goes through sn1, that is unimolecular substitution mechanism.
02:04
So the rate of the reaction depends largely on the stability of carbonyctoyne.
02:29
Intermediate.
02:35
So that means more stable will the carbocatoin and more will be the rate.
02:42
So part a here we will draw the structure of 3 bromo 1 butane.
02:50
So ch2 double bond ch ch chch 3 br.
03:02
So this is the structure of 3 bromo 1 butene.
03:13
So it will form the carbocatoins through resonance.
03:23
So the first carbocatoin formed is ch2 double bond ch, ch, th, th, th, th, th, th 3.
03:32
So here the positive charge is on the first carbon.
03:41
And the second carbotene or the resonating structure of this carbotoyne will be, ch2, 2, ch double bond, ch, ch, ch, th, th3.
03:59
So here, the positive charge is on this carbon.
04:05
So, here, now the two bromobutane, the structure is ch3, ch3, ch2, ch3.
04:24
So this is the structure of 2 -romo butane and it forms the carbocatoin as ch3, ch2, ch3...
