WebOct 26, 2015 · Bond strength usually refers to the energy required to break a bond homolytically--with one electron going to one of the atoms and the other electron going to the other atom. In the case of HF this requires more energy than in CH4. WebMar 30, 2024 · CH4 (or Methane) is a NONPOLAR molecule because all the four bonds (C-H bonds) are identical and CH4 has symmetrical geometry. Also the electronegativity difference of Carbon atom (C = 2.55) and Hydrogen atom (H = 2.2) is 0.35 (i.e 2.55 – 2.2 = 0.35), which is very less. Hence the CH4 molecule is a nonpolar molecule.

The bond-dissociation energy (BDE, D0, or DH°) is one measure of the strength of a chemical bond A−B. It can be defined as the standard enthalpy change when A−B is cleaved by homolysis to give fragments A and B, which are usually radical species. The enthalpy change is temperature-dependent, and the bond-dissociation energy is often defined to be the enthalpy change of the homolysis at 0 K (absolute zero), although the enthalpy change at 298 K (standard conditions) i… Web1 day ago · The Lewis structure of the methane (CH4) molecule is drawn with four single shared covalent bonds between the carbon and hydrogen atoms each.
