Answer to Problem 29E
The total number of σ bonds are 33 in AZT molecule
Explanation of Solution
There are two types of covalent bonds; σ bond and π-bonds. A σ-bond is formed by head-to head overlapping of hybridized orbitals. It is a strong bond and can exist between two bonded atoms. On the contrary, a π-bond is a weak covalent bond as it forms by side-way-overlapping of un-hybridized orbitals.
Since it is a weak bond therefore it is always exist with σ-bond in a double and triple covalent bond. A double covalent bond is formed by 1σ and 1 π bond whereas a triple covalent bond is formed by 1σ and two π bonds. In the given molecule, all single bonds are σ-bonds and all double bonds have 1 σ bonds. Therefore total number of σ bonds are 33 in AZT molecule.
