Linus Pauling noticed the the energy of a polar shortcut is often greater than expected. He attributed the better bond energy toa coulombic attraction between atoms with partially positive and negative charges. The better bond lengths that the heteronuclear bonds. Among the countless unexplainable phenomena that researchers encounter. The capability of heteronuclear varieties to form twin and triple bonds. The greater variety of valence electrons found in heteronuclear molecules. Answer
a.a coulombic attraction in between atoms v partially positive and negative charges.
You are watching: As bond order increases bond length
In molecules, together bond order increases,both link length and also bond energy increase. Both bond length and also bond power decrease. Bond length increases and also bond energy is unchanged. Bond length is unchanged and also bond power increases. Bond size decreases and also bond power increases. Answer
e.bond length decreases and bond power increases.

a. 1 b. 4/3 c. 5/2 d. 2 e. 3/2Answer
Use Lewis frameworks to predict the shortcut order for a sulfur-oxygen shortcut in the sulfite ion?
a. 1 b. 3/2 c. 4/3 d. 2 e. 5/2Answer
Based ~ above the following data, what is the F-F shortcut energy?
H2(g) + F2(g) → HF(g); ΔrH = –272.5 kJ/mol-rxn
Bond Bond power (kJ/mol)
a. 500 kJ/molb. 150 kJ/molc. –150 kJ/mold. –695 kJ/mole. 695 kJ/molAnswer
Cleavage of one H-H bond, (Delta H_1= 435 kJ/mol;)
Cleavage that one H-F bond, (Delta H_2= 565 kJ/mol;)
Formation of two F-F bonds, (Delta H_3= ?)
ΔHf of the reaction is = -272.5 kJ/mol = -545 kJ/2 mol
(Delta H_f=(Delta H_1+Delta H_3)-(2*Delta H_2))
(-545 = (435+Delta H_3)-(2*565))
(-545 = (435+Delta H_3)-1130) (585 = 435+Delta H_3)
(153 kJ = Delta H_3)
Using bond-energy data, what is ΔrH because that the following reaction?
CH4(g) + 2Cl2(g) → CCl4(g) + 2H2(g)
Bond Bond energy (kJ/mol)
a. –40 kJ/mol-rxnb. –150 kJ/mol-rxnc. 40 kJ/mol-rxnd. 1415 kJ/mol-rxne. 150 kJ/mol-rxnAnswer
a. –40 kJ/mol-rxn
Using the adhering to data reactions:
