Best Answer

12 sigma is actually 1.8 defects per 10^33 opportunities or if you subscribe to the bogus notion of the 1.5 sigma shift, it would be 4.3 defects per 10^26 opportunities. It is nonsense to talk about such things as no one would know how to measure or achieve such performance. The notion is only good for discussions when pontificating one's naval. 1.5 defects per million opportunities is the answer for 12 sigma. Its primarily used in the aviation industry.

How many sigma bonds are present in C6H12?

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.
