Which reaction product (A or B) is more likely to form in the epoxide ring opening reaction? Consider resonance structures.

Reaction product A is more likely to form in the epoxide ring-opening reaction

Explanation:

The diagram for the reaction can be seen in the image attached below.

An epoxide is any class of organic compound, cyclic ethers, having a three-membered ring; they are usually prepared by selective oxidation of alkenes or by ring-closure of halohydrins(any class of organic compound having a hydroxyl functional group and a halogen on neighboring carbon atom ) which are used in making plastic.
