Answer to Question #235016 in Organic Chemistry for muskan

Question

1)    Explain why cycloheptene though very unstable, can be made but cycloheptyne has never been made.

 

Answer 1

The smaller the carbon ring the more unstable it is. The reason for this is that the molecule cannot freely rotate about each bond. ... This molecule has the highest ring strain of all the carbon rings. A five membered ring such as cyclopentyne is not too far from that.
