Problem

The molecule shown below is called furan. It is represented in typical shorthand way for organic molecules, with hydrogen atoms not shown.

A pentagon-shape has an O at the point, arranged upward, and double bonds for the lower left and lower right sides.


What is the hybridization at each of the carbon atoms?

Solution

The shorthand way for organic molecules is called a bondline structure.

There are a number of rules for bondline structures but for the question in hand we only need to learn the 3 below:

1. "Corners" are carbons
2. Lines are bonds
3. Carbon needs 4 bonds to be neutral. When less than 4 bonds are visible in the structure, and carbon still doesn't have a formal charge (+ or -) then this means that there are hydrogens not shown that completes those 4 bonds.
