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.
the non polar solute gets dissolved as non polar solutes tend to dissolve in non polar solvents than in polar solvents. for eg: benzene(non polar solute) gets dissolved in carbon tetrachloride which is a non polar solvent but not in water because it is a polar solvent.
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.
