a)
Interpretation:
The major products formed during the addition of one equivalent of HCl to hexa-2, 4-diene along with the mechanism of their formation is to be shown.
Concept introduction:
Conjugated dienes undergo electrophilic addition reactions through the formation of an allyl carbocation. The allyl cation is resonance stabilized and the attack of chloride ion on each of these forms leads to the formation of a mixture of 1, 2- and 1, 4-addition products.
To show:
The major product formed during the addition of one equivalent of HCl to hexa-2, 4-diene along with the mechanism of their formation.
b)
Interpretation:
The major products formed during the addition of one equivalent of HX to 3-methylpenta-1, 3-diene along with the mechanism of their formation is to be shown.

To show:
The major products formed during the addition of one equivalent of HBr to 3-methylpenta-1, 3-diene along with the mechanism of their formation.
c)
Interpretation:
The major product formed during the addition of one equivalent of HCl to 1, 2-dimethylenecyclobutane, along with the mechanism of their formation is to be shown.

- It is not unexpected that the methoxyl substituent on a cyclohexane ring prefers to adopt the equatorial conformation. OMe H A G₂ = +0.6 kcal/mol OMe What is unexpected is that the closely related 2-methoxytetrahydropyran prefers the axial conformation: H H OMe OMe A Gp=-0.6 kcal/mol Methoxy: CH3O group Please be specific and clearly write the reason why this is observed. This effect that provides stabilization of the axial OCH 3 group in this molecule is called the anomeric effect.
