One of the first drugs to be approved for use in treatment of acquired immune deficiency syndrome (AIDS) was azidothymidine (AZT). How many carbon atoms are hybridized?

To find the solution we must establish the electronic configuration of all the elements present:

H = 1s1

C = 1s2 2s2 2p2

N = 1s2 2s2 2p3

O = 1s2 2s2 2p4

You can see hydrogen has only one electron, carbon has 4, in nitrogen it is five and in oxygen it is 6.

Explanation:

Hybridization in an atom can be achieved by locating the steric number of said atom. The sum of these atoms and the number of solitary pairs that atom has has the name of steric number. For example:

If the steric number of an atom is 4, that atom has a sp3 hybridization.

If the steric number of an atom is 3, that atom has a sp2 hybridization.

If the steric number of an atom is 2, that atom has a sp hybridization.
