What is the primary organic product formed when an oxirane (ethylene oxide) undergoes nucleophilic a — Alcohols Phenols and Ethers Chemistry Question

💡 Solution & Explanation

The Grignard reagent ($R^-$ nucleophile) attacks the less sterically hindered carbon of the highly strained oxirane ring, breaking the $C-O$ bond. Following hydrolysis, this process extends the carbon chain by exactly two carbons, yielding a primary alcohol ($R-CH_2CH_2OH$).
