How many pi bonds and sigma bonds are present in ritalin

I counted for pi bonds and 18 sigma bonds is that correct?

To determine the number of pi bonds and sigma bonds in a molecule, we need to analyze its structure. Ritalin, also known as methylphenidate, has a chemical formula of C₁₄H₁₉NO₂.

To count the number of sigma bonds, we look at the single bonds between the atoms. Each single bond represents one sigma bond. In Ritalin, there are 18 single bonds, so your count of 18 sigma bonds is correct.

Calculating the number of pi bonds requires identifying the presence of double or triple bonds in the molecule. A double bond consists of one sigma bond and one pi bond, while a triple bond consists of one sigma bond and two pi bonds. However, in Ritalin, there are no double or triple bonds present. Therefore, there are zero pi bonds in Ritalin.

In summary, Ritalin has 18 sigma bonds and zero pi bonds.
