Which bond in urea are polar?

Answer 1

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.

Answer 2

The formula for urea is H2N-C=O-NH2, so it has two amide bonds, i.e. O=C-NH2, and these are essentially peptide bonds, so the answer would be 2 peptide bonds. The caveat is that urea is not a dipeptide because the peptide bonds are not made from amino acids.

Answer 3

The bond between the carbon and oxygen atoms in urea is polar due to the differences in electronegativity between the two atoms. This results in a partial positive charge on the carbon atom and a partial negative charge on the oxygen atom.

Answer 4

it is the double bond between the Carbon and Oxygen

Answer 5

Covalent bonds.
