Polar
VSEPR Theory dictates that H2O is a "bent" molecule. Since the electronegativity of O is greater than H, the electron density of H2O is greater towards Oxygen. Thus, from both differences in electronegativity and the shape of the molecule, H2O is polar with a slight negative charge on O and a slight positive charge on the 2 H's.
H2O is a polar covalent molecule. It forms covalent bonds between the hydrogen and oxygen atoms, but due to the unequal sharing of electrons, the oxygen atom becomes slightly negative while the hydrogen atoms become slightly positive, leading to a polar molecule.
Toothpaste is typically a mixture of polar and non-polar substances. The surfactants in toothpaste are usually polar, while other ingredients such as thickeners and abrasives can be non-polar.
A polar solute is expected to be soluble in a non-polar solvent. This is because "like dissolves like" – polar molecules tend to dissolve in polar solvents, and non-polar molecules dissolve in non-polar solvents.
When a non-polar solute is mixed in a non-polar solvent, they will easily dissolve in each other due to their similar polarities. The solute molecules will distribute evenly throughout the solvent, forming a homogeneous solution. No strong interactions such as hydrogen bonding will occur between the solute and solvent molecules.
It is non polar. In amino acids, "polar" or "nonpolar" refers specifically to the side chain; the molecule as a whole is definitely polar, but leucine's side chain is a hydrocarbon with no polar groups.

Every molecule has a polarity. They can either be non-polar (same on both sides) or polar (different on both sides). For example the molecule CO2 is a non-polar molecule. H20 (water) is a polar molecule (due to Valence Shell Electron Pair Repulsion theory (VSEPR)).
C2H6 is the hydrocarbon ethane, and it has very low solubility in water. Most hyrdocarbons are like this. They're non-polar and so can't associate with the highly polar ends of the H20 molecules. Ethane would be soluble in a non-polar solvent such as benzene (C6H6).
Yes, both ch3ch2ch2ch2ch3 and ch3ch2ch2ch2ch2ch3 are miscible since they are both alkanes with similar intermolecular forces. CBr4 and H2O are immiscible because CBr4 is nonpolar while H2O is polar, resulting in different intermolecular forces that prevent them from mixing. Cl2 and H2O are immiscible because Cl2 is a nonpolar molecule while H2O is polar, leading to differences in intermolecular forces that hinder their ability to mix.
non-polar
It is non polar.
Polar contains polar. Non-polar contains nothing.
ClO4 is polar.
Nonpolar
It is non-polar, covalent.
H2O is a polar covalent molecule. It forms covalent bonds between the hydrogen and oxygen atoms, but due to the unequal sharing of electrons, the oxygen atom becomes slightly negative while the hydrogen atoms become slightly positive, leading to a polar molecule.
