come on eureka tihis one is damn eaasy.
its a conjugated diene system, so 1,4- addition is obvious
at high remperature 1,2 product is more favoured
in general, at low temperature we get product controlled by chemical kinetics where as at high temperature we get a thermodynamics controlled prduct
whats that +1/2 and -1/2 ??????????does that signify equal probablity of attack or equal distribution of positive charge on conjugated system???????[7]
no , It' signifies that the charge is distributed over the 2 carbons equally.
remember SE reactions ? That's y I wrote not totally correct.
1,2 product :A: kinetic product
1,4 product :B: thermodynamic product
