Q1-1-44E - Organic Chemistry (Mcmurry)

Question

Quetiapine, marketed as Seroquel, is a heavily prescribed antipsychotic drug used in the treatment of schizophrenia and bipolar disorder. Convert the following representation into a skeletal structure, and give the molecular formula of quetiapine.

Step-by-Step Solution

Answer

Skeletal structure of Quetiapine (Seroquel)

Skeletal structure

In order to convert to a skeletal structure, there are three simple rules. The first is that every carbon becomes a point at the intersection of two lines. The second is that for sp²and sp³ carbons, those two lines intersect roughly 120⁰and the angle for sp carbons is 180⁰. 

Skeletal structure of given compound

The third rule of skeletal structure is that all atoms that are not carbon or hydrogen bonded to carbon will remain in the structure. The molecular formula of the compound is C₂₁H₂₅N₃O₃S. The skeletal structure is represented as follows:
