Answer:
(a) CH3CH2CH2CH2CH3(l)
(b) CH3CH2OH(l)
- Dipole-dipole interaction
- Dispersion forces
- Hydrogen bonding
(c) H2CO(l)
(d) O2(l)
Explanation:
Dispersion forces are those forces that occur between two non polar molecules.They form the weakest bonds.Here electrons of one molecule is attracted to the nucleus of the other molecule. Example are;
- Interaction of two methyl (-CH₃) group
- Interaction between nitrogen gas , N₂ molecules
- Interaction between oxygen gas ,O₂ molecules
Dipole-Dipole interaction happens when two polar molecules interact.Positive charges in one molecule is attracted to negative charge of another molecule.Examples
- Chloroform (CHCl₃)
- Ammonia (NH₃)
Hydrogen bonding are created when an hydrogen atom bonded to an electronegative atom is attracted to a another electronegative atom.Example is the hydrogen bond between oxygen atom and hydrogen is water (H₂O).
Answer:
Thus, helium has the largest first ionization energy, while francium has one of the lowest.
If the angle is either 0 or 180, that means that there is either negative or positive work, so A and D are not correct.
If the angle is 45, then there is still some work involved.
The only option where there is no work done by a force is B. when the angle is between the force and displacement is 90.
