4. bond order

2.. Which pair of bonded atoms has the highest bond dissociation energy?

Group of answer choices

a. F2(g) --> F(g) + F(g)

b. N2(g) --> N(g) + N(g)

c. O2(g) --> O(g) + O(g)

3.. Which bond is the strongest?

Group of answer choices

a. Si−Cl

b. C−Cl

c. Ge−Cl

4.. For any element, X, which statement is true about the attraction between two bonded X atoms?

Group of answer choices

a. Energy is released when a bond between two X atoms breaks

b. Energy is always required to break the attraction between two bonded X atoms

c. Energy is required to break the attraction between two bonded X atoms sometimes. It depends on how attracted the elements are.

Answer 1

1) Factons account for bond strength a) Difference in electronegativity b) Bond length c) Bond order . All these factors affect the bond strength 2) Highest bond dissociation energy 1. b) ab (g) N(g) + N(9) :NEN: 3) strongest Bond 1 of electronegativity difference two booded atoms is large then that Bond is strongest. Because higher difference makes the compound ionic in nature. si-dl 3.0-1.40 = 101 – Bond is stoongest Crd 3.0-2.55 +0:45 Gerd 3:0-8-01 = 0.99 A) Attraction between two bonded x atoms b) Energy is always required to break the attraction between two bonded x' atorms. .
