Question

The enolic form of ethyl acetoacetate as given below has :

• A. 18 sigma bonds and 2 pi-bond
• B. 9 sigma bonds and 1 pi-bond
• C. 9 sigma bonds and 2 pi-bonds
• D. 16 sigma bonds and 1 pi-bond

Answer 1

The correct option is A 18 sigma bonds and 2 pi-bond

In enolic form of ethyl acetoacetate has 16 single bonds i.e., 16 sigma bond and 2 double bonds i.e., 2 sigma bonds and 2 pi bonds.
Hence, the given structure has 18 sigma bonds and 2 pi bonds.
