Question

Define bond length and bond enthalpy

Answer 1

Answer:

In chemistry, bond energy, also called the mean bond enthalpy or average bond enthalpy is the measure of bond strength in a chemical bond. IUPAC defines bond energy as the average value of the gas-phase Bond-dissociation energy for all bonds of the same type within the same chemical species.

In molecular geometry, bond length or bond distance is defined as the average distance between nuclei of two bonded atoms in a molecule. It is a transferable property of a bond between atoms of fixed types, relatively independent of the rest of the molecule.

Answer 2

Answer:

1. Bond Enthalpy : Amount of energy required to break 1 mole of bond of perticular type between 2 atoms in gaseous state.
2. Bond length : The equilibrium distance between the nuclie of 2 bonded atoms in a molecule.
