Ionic compounds are composed of groups of cations and ions and sometimes water molecules arranged into energetically favorable 3D arrangements, i.e. a crystal lattice. The overall stability of the lattice is called the lattice energy.
Water, as a polar molecule with a high dielectric potential, is prone to interact with ions via ion-dipole interactions with up to six water molecules interacting with one metal ion. If the sum of the interactions taking place between the ions and water molecules exceeds the lattice energy of the ionic compound, then the compound is water soluble.

UREA (H2 N - C(O) - NH2) is polar for two reasons:
The bond whose participants have the greatest electronegativity difference is the CARBON-OXYGEN DOUBLE BOND.
The polarity of this bond is made even greater by the donation of the lone pairs of the nitrogen atoms into the antibonding orbital of the pi-bond of the double bond between carbon and oxygen. This results in a partial positive charge on both nitrogen atoms, along with a partial negative charge on the oxygen atom. Protonation of urea in acid occurs on oxygen.

The way the term “polar molecule” is used in biochemistry is perhaps not rigorous. In common usage, it refers to the density of polar functional groups on the molecule, not the net polarity of the molecule. Closely related to that is the number of hydrogen bonds the molecule makes with water and how soluble it is in water.

Because water is a very polar molecule, the oxigen atom of water has a partially negative charge which attracts positive ions, the idrogen atoms of water have a partially positive charge which attracts negative ions, so the ionic bond is dissociated by the molecules of water.

first you need to know about polar bonds take two very contrasting elements one which has extreme affinity to gain a electron ( electropositive) and the other being having extreme abhor for electrons one who wants to donate electron ( electronegative) and you will get a polar compound
Na Cl is a very polar compund because its components are highly electropositive ( low el.ectromegativity) and highly electronegative respectively
LiF however is a wonderfull example to study dipole moments and conjugate it with polar.( because all data is available online)
CsF is however the most polar bond known to homosapiens EN DIFF 3.3
To find out polarity just substract the electronegativity of the two components of bond
When comparing a multicomponent compund things become complex

Lone pair of electrons present on nitrogen involves in the resonance which results into formation of two poles..Hence it becomes polar.
Also due to difference in electronegativity of carbon, oxygen and nitrogen their is inductive effect which results into polarisation of bond.
