The treatment of 1,4-dimethycyclohepta-1,3-diene with one equivalent of HBr at the elevated temperature given 1,2-adduct rather than 1,4-adduct should be explained. Concept Introduction : The compound which has more substituted pi bond ( thermodynamic product or major product) at high temperature is predominant.

Dehydrohalogenation of 1-chloro-1-methylcyclopropane affords two alkenes (A and B) as products. Explain why A is the major product despite the fact that it contains the less substituted double bond.

the product obtained from the reaction of 1,3-butadiene with cis-1,2-dichloroethene O because it is a meso compound O because is has no asymmetric centers O because it is a racemic mixture O because it has a point of symmetry the product obtained from the reaction of 1,3-butadiene with trans-1,2-dichloroethene O because it is a meso compound Obecause is has no asymmetric centers Obecause it is a racemic mixture because it has a point of symmetry

When buta-1,3-diene (CH2 = CH – CH = CH2) is treated with HBr, two constitutional isomers are formed, CH3CHBrCH = CH2 and BrCH2CH = CHCH3. Draw a stepwise mechanism that accounts for the formation of both products.
