Urea is an organic compound widely used as a fertilizer. its solubility in water allows it to be made into aqueous fertilizer solutions and applied to crops in a spray.

what is the maximum theoretical number of water molecules with which one urea molecule can hydrogen bond? (exact whole number required.)

One urea molecule can make hydrogen bonding with 8 water molecules

Explanation:

Hydrogen bonding takes place between lone pair of electronegative atoms (O,N and F) and H atom attached with those electronegative atoms.Draw the lewis structure of urea and determine how many lone pairs and H atoms are available for hydrogen bonding formation.Theoretically one urea can make hydrogen bonding with 8 water molecules.Representation of hydrogen bonding has been given below.
