Problem: Indigo is the dye used in coloring blue jeans. The term navy blue is derived from the use of indigo to dye British naval uniforms in the eighteenth century. The structure of the indigo molecule isa. How many σ bonds and π bonds exist in the molecule?

FREE Expert Solution

Sigma (σ) bonds are the single bonds in molecules. Also, recall that a double bond is composed of 1 σ bond and 1 π bond and a triple bond is composed of 1 σ bond and 2 π bonds


Indigo has:

  • 22 single bonds  22 δ bonds
  • 8 double bonds
    • 8 δ bonds
    • 8 π bonds
