The structure of urea determines its polarity. The C=O portion of the molecule is polar, as well as the two N-H bonds on the opposite end. Therefore urea is a polar molecule.
Refer to the related links for an illustration.
Hydophilic is to be a "water loving" compound, and urea certainly fall i this category. If we look at the chemical groups of two amides and a carbonyl, urea is likely to H-bond with water and maintain solubility at high concentration.
Yes, the most polar one being between the carbon and oxygen
Ammonia is polar
Polar
Yes
no
Polar
Molecules that contain two covalent bonds are sometimes polar.
Most of hydrocarbon oils, such as coconut oil or vegetable oil contain only non polar bonds.
A solvent is polar if its molecules contain highly polar covalent bonds, for example water, or ionic bonds, for example molten salt.
The answer is yes, because molecules get polarity after forming polar covlent bond,no such polar molecules can exist which do not contain polar covalent bond. Am I right?

H2S and NO2H2sNO2-
If you mean "what type of bonding is present in urea?" then the general answer is covalent bonds. The carbon is sp2-hybridized. The C=O bond is a double bond (a carbonyl group) while the C-N bonds are single but have significant double bond character leading to a planar (flat) structure. The C-H bonds are single bonds. In terms of intramolecular bonding, there are hydrogen bonds between urea molecules (each carbonyl oxygen accepts 4, from N-H hydrogens). This leads the urea's high solubility in water.
No, methane has no polar hydrogen atoms to create hydrogen bonds.
Yes, a molecule can be nonpolar when it contains polar covalent bonds, because think about it. if the molecule is linear in structure, and it has two equally polar bonds on either side, then the polarity will essentially cancel out, and it will become nonpolar.
Yes, the molecule does not contain polar bonds on the Aluminum and there are no lone pairs. The elements attached to the Aluminum have the same electronegativity.
