Is the bond overlap larger for Cl2 than for F2? Why is that Thank you
Cl2 has a longer, weaker bond than Cl2+ (Cl2: 1.988 Å, Cl2+ : 1.8917 Å). Furthermore, Cl2+ has higher bond dissociation energy (Cl2: 57.18 kcal/mole, Cl2+ : 99.2 kcal/mole). Use molecular-orbital theory to predict the bond order for each of these molecules and explain why Cl2+ has higher bond dissociation energy.
the standard molar enthalpy of ClF3 is -400kj/mol. the bond enthalpies of cl2 and f2 are 230 kj/mol and 160 kj/mol. Calculate the Cl-F bond enthalpy
Question 3 1 pts Given the bond dissociation energies (in kJ/mol) for the following diatomic molecules Cl2 (243), F2 (158), H2 (436), O2 (498), N2 (945) choose the one(s) that could be broken by using blue light (=465 nm). F2 and Cl2 o F2 F2, C12, H2, O2 and N2 F2, Cl2 and H2 F2, Cl2, H2 and 02
Name Question/6 Why is F2 a stronger oxidant than Cl2 under standard conditions? Answer by constructing a thermodynamic (or Hess) cyele (write out the equations generically using X to represent the halogen) and justifying the relative values for F vs. Cl in each. Some important information includes ?IENF)=-328 kJ/rmol. ?{ENC,--349 kJ/mol, E.F2F--2.87, E"coor-1.36. Half-cell reaction: Thermodynamic cycle component 1 Thermodynamic cycle component 2: Thermodynamic cycle component 2: Final justification: 41 CHAT
[25] Question 3 3 (a) The bond dissociation enthalpies for C, and F2 are 614 kJ/mol and 154 kJ/mol respectively Using an argument based on Molecular Orbital Theory, explain why C2 has a much larger bond dissociation energy than F2 Illustrate your answer with suitable MO diagrams (10)
Why aren't heavier elements much larger than lighter elements? Why aren't heavier elements much larger than lighter elements? Larger nuclear forces pull the electrons into closer orbits. Larger gravitational forces pull electrons into closer orbits. The larger positive charge in the nucleus pulls the electrons into closer orbits. Larger magnetic forces pull electrons into closer orbits.
How much faster would fluorine gas (F2) escape from a small hole than chlorine gas (Cl2)? 0.536 times 3.48 times 1.37 times 1.87 times
1. Using bond energies, calculate ΔH for the reaction below. CH4(g) + Cl2(g) + F2(g) ---- CF2Cl2(g) + HF(g) + HCl(g) 2. Which of the following likely to be more soluble in water? Circle your pick. a) C6H12 or C6H12O6 Explain: b) CH3CH2COOH or CH3CH2COONa Explain: c) HCl or acetic CH3CH2Cl Explain:
When the coupon interest rate is larger than the YTM, the bond is a
Why do you think that the enthalpy of vaporization for water is so much larger than the enthalpy of fusion? Hint: Think about intermolecular forces.
