Problem: One of the first drugs to be approved for use in treatment of acquired immune deficiency syndrome (AIDS) was azidothymidine (AZT). Complete the Lewis structure for AZT.d. How many δ bonds are in the molecule?

FREE Expert Solution

Complete Lewis structure → includes lone pairs


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

  • There are:
    • 28 single bonds → 28 σ bonds
    • 5 double bonds:
      • 5 σ bonds
      • 5 π bonds
