Answer:
Dipole-dipole interactions : occur between polar molecules
Dipole-induced dipole interactions: occur between polar and nonpolar molecules
London dispersion forces: occur in all substances, but are the most important in nonpolar substances
Hydrogen bond: electrostactic attraction between a hydrogen atom and a highly electronegative atom
van der Waals forces: electrostatic interactions between partially charged regions of a molecule
I believe cc would result in a recessive pair.
The increase in size and changes in shape of a developing organism depend on the increase in the number and size of cells that make up the individual. Increase in cell number occurs by a precise cellular reproductive mechanism called mitosis.
Answer:
CCl4 - Nonpolar
CH3OH - polar
NH3 - polar
CS2 - Nonpolar
Explanation:
One important thing that we should know is that polarity has to do with the presence of a resultant dipole moment in a molecule.
Dipole moment is a vector quantity, This means that its direction is also taken into account when discussing the dipole moment of molecules.
Hence, symmetrical molecules such as CS2 and CCl4 are non-polar even though they have polar bonds because their dipoles cancel out(zero resultant dipole moment).
On the other hand, NH3 and CH3OH are non-symmetrical molecules hence they possess an overall dipole moment and are polar molecules.
