If bonding occurs in this state, the 3 equivalent p electrons would form 3 equivalent bonds oriented at 90o to each other, and the s electron would form a bond of a different type and orientation from the other three. CH2Cl2 is the chemical formula for DCM. The orientation of the two pi bonds is that they are perpendicular to one another (see Figure 6 below). Because its shape is tetrahedral, the bond angle is 109.5 degrees Does whmis to controlled products that are being transported under the transportation of dangerous goodstdg regulations?
