Concept Introduction:
>In comparison to simple ethers,
On reacting with anionic nucleophiles, epoxides form ring-opened products. This reaction is quite rapid and is exothermic in nature.
>The high reactivity of epoxides towards anionic nucleophiles is due to the presence of angle strain in epoxide and this is relieved by opening of the ring.
