In the following reaction, final product is

Ethoxy ethane with dil. ${\mathrm{H}}_2\mathrm{S}{\mathrm{O}}_4$ gives

In products $\mathrm{A} \mathrm{and} \mathrm{B}$, nitro group is attached to

Epoxides (or oxiranes) are three membered cyclic ether's and differ from other cyclic and acyclic ether's in that they are reactive to various reagents. The reason for this reactivity is the strained three membered ring. Reactions with nucleophiles can result in ring opening and relief of strain. Nucleophiles will attack either of the electrophilic carbons present in an epoxide by an $S_{N}2$ reaction.



A and B are
