Hi everyone here we have a question telling us that four and it's all to hide. C eight H. A. 02 is a colorless volatile liquid that gives anna seated sweet floral smell. The structure of four ANAs al to hide is shown below. And our goal is to determine the number of valence electrons utilized by this adam utilized by atoms in this molecule for making sigma bonds. So first let's count how many sigma bonds. Every single bond is a sigma bond and every double bond has one sigma and one pi bond. So let's count these. We have 10 11, 12, 13, 14, 15, 16, 17 and 18 Sigma bonds. So we have 18 sigma bonds and one sigma bond equals two electrons. So the total valence electrons and sigma bonds is going to be 18 times two, Which is 36. And that is our final answer. Thank you for watching. Bye.
