Current Question (ID: 10822)

Question:

$\text{The enolic form of ethyl acetoacetate is given below. The number of sigma and pi bonds in the enolic form of ethyl acetoacetate are -}$

Options:

1. $18 \text{ sigma bonds and } 2 \text{ pi-bonds}$ (Correct)
2. $16 \text{ sigma bonds and } 1 \text{ pi-bond}$
3. $9 \text{ sigma bonds and } 2 \text{ pi-bonds}$
4. $9 \text{ sigma bonds and } 1 \text{ pi-bond}$

Solution:

$\text{Hint: Double bond contains one sigma and one pi bond.}$ $\text{The enolic form of ethyl acetoacetate has 16 single bonds i.e. 16 σ-bonds and 2 double bonds i.e,}$ $2 \text{ σ-bonds and } 2 \text{ π-bonds. Hence, the given structure has } 18 \text{ σ-bonds and } 2 \text{ π-bonds.}$ $\text{The structure shows the detailed bond analysis with sigma and pi bonds labeled.}$
