Problem: The molecule shown below is called furan. It is represented in typical shorthand way for organic molecules, with hydrogen atoms not shown.How many valence electrons are there in the molecule?

FREE Expert Solution

We're being asked to determine the number of valence electrons of furan.

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

We are given the shorthand notation of the Lewis structure for furan

Recall: A Lewis Dot structure, named after Gilbert N. Lewis, is the structural representation of a molecule that involves the use of valence electrons by the involved atoms in the creation of covalent bonds.
