Sir in these structures positive charge appears on c2 and c4 but then also they have put positive charg. on whole carbon of resonance hybrid 1,

1, 3-Butadiene This intermediate carbocation is allylic in nature and hence can be regarded as a resonance hybrid of two equivalent structures ( and II) : CH4CHCH-CH,Br CH-CH = CH-CH,Br = CH,-CH-CH-CHBr 2 II 3 Resonance hybrid Step 2. Since in the resonance hybrid, the positive charge is almost equally distributed between caro atoms as indicated in 1 and lI, the attack of bromide ion can occur on either of these. If the attack occurs CL2-addition product results and if it occurs on C 1 Ladditi

    actually positive charge distribution takes place between C1 and C3 carbon via resonance. and we know that in resonance p orbital of all the three carbon of allyllic carbocation participate so the + charge also distribute via C2 carbon. and hence we show Complete +ve charge on all three carbon or partial +ve charge on C1 and C3 carbon.

    it's simple mean distribution of charge note two explain which carbon content positive and which carbon not contain.the resonance hybrid positive charge so movement of positive charge not there position

    but positive charge is on only two carbons center vale carbon pe ni hai to whole distribute kaise hua

    it's mean charge distribute all over structure during resonance. resonance hybrid explain that in resonating structure all over structure have positive charge
