Conjugation in Alkadienes & Allyic Systems
I am having trouble determining the difference between vinylic & allylic hydrogens in a Cyclohexene, how many of each, what determines it?
Second, what is the best way to determine a conjugated diene...are there any rules?
In 1,1-dimethylallyl the cation is positive...which type of carbon is that...tertiary?
In 1,3-butadiene is the activation Energy around the C-C central bond around 4 kcal/mol?
And in the Diels-Alder reaction between 1,3-butadiene and ethene would the product be 1,4-hexadiene?
