Suppose that the C=O group in a peptide bond can be regarded as isolated from the rest of the molecule. Given that the force con
stant of the bond in a carbonyl group is 908 N m−1 , calculate the vibrational frequency of (a) 12C=16O and (b) 13C=16O.

Answer and Explanation:
Epoxide is a three membered ring made up of two carbon atoms and one oxygen atom. Epoxides are cyclic ethers. Due to its ring size, it is highly strained and very reactive. Epoxide ring opening takes place with respect to addition of acid and base.
Ring opening of epoxide with acid:
In the presence of base, the nucleophile attacks the epoxide ring at more substituted site and inverse stereochemistry takes place.(check file 2 attached)
Ring opening of epoxide with base:
The backside attack of nucleophile takes place in less substituted site and then it undergoes protonation to form a product.
