From the given set of species the species that obey the conditions for the greenhouse gas should be determined. Concept introduction: Greenhouse effect: The heat near the earth surface gets trapped by the gases present in the earth atmosphere. The carbon dioxide is the primary gas that traps more heat. Conditions that greenhouse gas should fulfil is as follows, The gas is considered as greenhouse gas if it possesses dipole moment or the vibrational motions of the gases should create some temporary dipole moment. Atmosphere: The atmosphere is defined as air that is layer of gases which surrounds the earth due to gravity of earth. The earth atmosphere consists of layers such as thermosphere, mesosphere, stratosphere and troposphere depending on the temperature and its composition. Dipole moment: It is the measure that describes the separation and the magnitude of charges in polar (a material is considered as polar if it has charge separation) molecule. Bond Enthalpy: The energy required in order to form the bond between the two atoms is called bond enthalpy. Bond Dissociation Energy : The minimum energy required to break a bond between two atoms present in the molecule is called bond dissociation energy.

Answer 1

Question

Formula Formula Bond dissociation energy (BDE) is the energy required to break a bond, making it an endothermic process. BDE is calculated for a particular bond and therefore consists of fragments such as radicals since it undergoes homolytic bond cleavage. For the homolysis of a X-Y molecule, the energy of bond dissociation is calculated as the difference in the total enthalpy of formation for the reactants and products. X-Y → X + Y BDE = Δ H f X + Δ H f Y – Δ H f X-Y where, ΔHf is the heat of formation.
