(a) 16 sigma bonds and 1 pi - bond
(b) 9 sigma bonds and 2 pi - bonds
(c) 9 sigma bonds and 1 pi - bond
(d) 18 sigma bonds and 2 pi - bonds

Answer 1

option d 18 sigma and 2 pi bond and 1st structure is enol and 2nd is keto form alag hai but bond no. same stability different hoti hai

Answer 2

Answer:

d) 18 sigma bonds and 2 pi - bonds

Explanation:

The organic compound ethyl acetoacetate (EAA) is known as the ethyl ester of acetoacetic acid. It is majorly used as a chemical intermediate in the production of variety of compounds, like the amino acids, analgesics, antibiotics, and even vitamin B1. The compound is also used in the manufacture of dyes, inks, perfumes, yellow paint pigments and plastics.

In an enolic form of ethyl acetoacetate there are 16 single bonds, which means 16 sigma bonds and two double bonds, ie. two sigma bonds and two pi bonds.

Hence, the given structure has 18 sigma bonds and 2 pi - bonds.
