Hello, good evening students.
00:03
So, four geometrical isomers to exist, we have a structure like, so if we have the c double bone c, then it should be a, it should be b, it should be c and it should be d.
00:28
All four groups are different only than all four groups along pi bond should be different.
00:48
Only then gi can exist only then gi can exist okay so let's check with the options in the first option we have but 20 so beaut 1e so its structure will be like something like this beaut and we have hydrogen here hydrogen here ch3 ch2 and h so here we have same group two hydrogen group so no g .i.
01:36
No geometrical isomer is.
01:37
Okay.
01:39
In b option, we are given bute 2 in.
01:44
So, bute 2 in will be like this...
