Which of the following is least likely to be formed as a product when 2-iodopentane reacts with sodium ethoxide?

Question

Quizplus · Accepted Answer

When 2-iodopentane reacts with sodium ethoxide, it undergoes a substitution reaction to form ethoxy pentanes and an elimination reaction to form pentenes. The least likely product is 1-ethoxypentane because the reaction favors the formation of products through a bimolecular nucleophilic substitution (SN2) mechanism at the primary carbon or elimination (E2) to form alkenes, making the substitution at the secondary carbon (to form 2-ethoxypentane) or the formation of alkenes more likely.
