Question

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

Answer 1

Vanillin is an organic compound with the molecular formula $C_8H_8O_3$. It is a phenolic aldehyde with functional groups including an aldehyde, hydroxyl, and ether, and is the primary component of vanilla bean extract.
Structure of Vanillin:
$\text{HO-C}_6H_3(\text{OCH}_3)\text{CHO}$
Counting oxygen atoms and $\pi$ electrons:
Total number of oxygen atoms = 3.
Total number of $\pi$-bonds = 4 (one in the carbonyl group and three in the benzene ring).
Since each $\pi$-bond has two $\pi$-electrons:
$\text{Total number of $\pi$-electrons} = 4 \times 2 = 8$
Therefore, the sum of oxygen atoms and $\pi$-electrons is:
$3 + 8 = 11$
