In these two molecular orbitals the energy of one orbital is greater than the the atomic orbitals which is known as sigma antibonding orbital while the energy of the other orbital is less than the atomic orbital this orbital of lower energy is called sigma bonding orbital and the shared electron are always present in the sigma bonding orbitals. BSc-2nd Year. The main characteristics properties of covalent compounds are as follows. Due to strong attractive forces between ions a larger amount of energy is required to melt or to boil the compound and hence the melting and boiling point of the ionic compound are generally high. There are three types of overlapping in the formation of sigma bond. 90% of more than 30 million chemical compounds contain carbon.
