In C6H12, each carbon atom forms four sigma bonds, and hydrogen forms one sigma bond. Since there are 6 carbon atoms and 12 hydrogen atoms present, the total number of sigma bonds would be (6 carbon atoms x 4 sigma bonds per carbon) + (12 hydrogen atoms x 1 sigma bond per hydrogen) = 24 + 12 = 36 sigma bonds.
There is no company called Six Sigma Program, instead Six Sigma is a set of tools used by business and others that improves process outputs by identifying and removing error and reducing variability in manufacturing and business processes.
