WebBond energy is the energy required to break a covalent bond between two atoms. A high bond energy means that a bond is strong and the molecule that contains that bond is likely to be stable and less reactive. More reactive compounds will contain bonds that have generally lower bond energies. Some bond energies are listed in the table below. WebThe nitrogen lone pair, therefore, is more likely to break away and form a new bond to a proton – it is, in other words, more basic. Once again, a more reactive (stronger) conjugate base means a less reactive (weaker) conjugate acid. czech republic visa application form from uaehttp://butane.chem.uiuc.edu/pshapley/GenChem1/L9/web-L9.pdf binghamton university bthere
