Question

The following model is a representation of ibuprofen, a common over-the-counter pain reliever. Indicate the positions of the multiple bonds, and draw a skeletal structure (gray 5 C, red 5 O, ivory 5 H).

Short answer

In ibuprofen structure carbon-1(C1), C4, C5, C6, C7, C8, C9 contains multiple bonds means double bond in ibuprofen structure.

Step-by-step solution

Multiple bonds

Multiple bonds are chemical bonds that are formed by sharing two or more electron pairs.

Multiple bonds indicate either double or triple bonds. If a double bond is present then one bond is sigma $\left(\sigma \right)$and the other is pi $\left(\pi \right)$. If a triple bond is present one bond is$\sigma$ and the other two bonds are $\left(\pi \right)$-bonds.

Positions of, multiple bonds in ibuprofen

ibuprofen

In an ibuprofen structure C1, C4, C5, C6, C7, C8, C9, contains multiple bond. In case of ibuprofen these position contains double bonds.

Skeletal structure of ibuprofen

Skeletal structure in organic chemistry is a series that shows the series of atoms bonded together to form the structure of a compound.

In simple words, the skeletal structure includes only bonds and atoms other than carbon and hydrogen. The skeletal structure of ibuprofen is as shown below;
