Washington, D.C., formally the District of Columbia and commonly referred to as Washington, the District, or simply D.C., is the capital of the United States. The signing of the Residence Act on July 16, 1790, approved the creation of a capital district located along the Potomac River on the country's East Coast.
Now three of these sp 3 hybrid orbitals form sigma bonds by overlapping with three 1s orbitals of the three hydrogens and the remaining sp 3 hybrid orbital forms a sigma bond by overlapping with the sp 3 hybrid orbital of the other carbon which also has three Hydrogens bonded to it in the similar manner.
Double and triple covalent bonds are stronger than single covalent bonds and they are characterized by the sharing of four or six electrons between atoms, respectively. Double and triple bonds are comprised of sigma bonds between hybridized orbitals, and pi bonds between unhybridized p orbitals.
