Hi, I need help with my chemistry homework. This has to do with chemical bonding. These are only some of the questions the teacher gave me.
Describe:
The force that bonds two hydrogen atoms in a hydrogen molecule, H2
The relationship between the bond energy of a molecule and its bond strength
Which is more stable, compounds with high bond energies or low bond energies
Given the following bond length:
Molecule
1. F2
2. Cl2
3. Br2
4. I2
Bond Length
1. 141 pm
2. 199 pm
3. 228 pm
4. 267 pm
Bond Energy
1. 156 KJ/mole
2. 243 KJ/mole
3. 193 KJ/mole
4. 151 KJ/mole
Explain the general trend that a bond length increases the bond energy decreases going from F2 to I2
Chorline has a longer bond length than fluorine yet it has a higher bond energy, why?
Given the following,
Molecule
1. H-F
2. H-Cl
3. H-Br
4. H-I
Bond Length
1. 92 pm
2. 127 pm
3. 141 pm
4. 161 pm
Bond Energy
1. 569 KJ/Mole
2. 432 KJ/Mole
3. 366 KJ/Mole
4. 299 KJ/Mole
The N-N and O-O single covalent bonds aremuch weaker than the C-C single covalent bond. Explain.
Which are more stable, compound with high bond energies or compounds with low bond energies?
I'll show the rest later.
