Add a halogen to the correct carbon based on the direction. The result will always be a non-negative, nonfractional number. Steps to calculate DBE- Insert the number of Carbon (C), Hydrogen (H), Nitrogen (N) and Halogen (X) in the formula-. Example: a) For Molecular formula C5H10 = (2C + 2 + N -H - X)/2 = (2 x 5 + 2 - 10)/2 = (12-10)/2 = 1.

The second problem (bottom arrow) is that the joint between single and double bond doesn't look fine, even when I'm using the comand: bond join = true . Because of the relative weakness of the germanium–germanium double bond, the metathesis reaction can be induced by heating without requiring a catalyst to drive the process.

Because of the large number of electrons, double bonds tend to be reactive. In chemical bonding: Formation of σ and π bonds. A double bond corresponds to a σ bond plus a π bond, and a triple bond corresponds to a σ bond plus two π bonds.
