Vanillin compound obtained from vanilla beans, has total sum of oxygen atoms and π𝜋 electrons is ______

The vanillin compound, C8H8O3, has 3 oxygen atoms.

In terms of pi (π) electrons, we need to look at the double bonds and the aromatic ring in the structure of vanillin.

The aromatic ring (benzene ring) has 6 π electrons, and there are 2 double bonds in the aldehyde group and the ether group, each contributing 2 π electrons.

So, the total number of π electrons is 6 (from the benzene ring) + 2 (from the aldehyde group) + 2 (from the ether group) = 10 π electrons.

Therefore, the total sum of oxygen atoms and π electrons in vanillin is 3 (oxygen atoms) + 10 (π electrons) = 13.
