Question
IN-CLASS EXERCISE 5-MOLECULAR SHAPE AND STRUCTURE Page | 103 t also can be defined as the energy released when a bond s formed. Look up 1. Bond the bond energles for Na, O, and F, in the Handbook of Chemistry and Physics. ist the three molecules in increasing order of bond energies. does this information relate to the relatively low reactivity of Na gas at room temperature? a. Relate this order to the Lewis structures for the three molecules. How up the term nitrogen fixation on the Internet or in any reliable source. Explain how the bond energy and stability of N2 is related to this biological process. 2. In part D1 of the experiment, you built two identical molecules a. After taking the action you did in part D2, do you think that the two molecules are now identical? Why or why not? 29Explanation / Answer
bond energy of
N2: 945 Kj/mol
O2: 498 KJ/mol
F2:157 KJ/mol
increasing order of bond energy is F2< O2 < N2
as there is three bond between two nitrogen atom, the bond eenrgy is maximum, where as number of bond between two oxygen and fluorine atom is two and one respectively.Besides, the size of fluronie atom is smalest and as a result the lone pair repulsion is maximum in fluorine which is also responsible facor for lowest bond energy.
