Which Bond Can Break Most Easily

Question

Which bond can break most easily?  
A) Ionic bond
B) Covalent bonds
C) Polar covalent bond
D) Hydrogen bond
E) Magnetic bond

Accepted Answer

Hydrogen bonds are the weakest among the given options. Hydrogen bonding occurs when a hydrogen atom bonded to strongly electronegative atoms like Fluorine, Oxygen, or Nitrogen, is attracted to another electronegative atom in another molecule. As compared to ionic, covalent or polar covalent bonds, hydrogen bonds have relatively low bond energies which allow them to break more easily.
