Sort by:

The bond between $$Na$$ and $$O$$ will be ionic in nature due to the greater electronegativity difference between the two and also due to the low Ionization Enthalpy of $$Na$$ and high electron affinity of $$O$$. The bond between $$O$$ and $$H$$ will be a polar covalent bond according to the Fajan's Rule as the size of $$H$$ is very small and the electrons are pulled more towards $$O$$ as it has greater electronegativity.

When $$NaOH$$ is dissolved in $$H_2 O$$ it dissociates into $$Na^+$$ and $$OH^-$$ ions, thus showing that ionic bond breaks in a polar solvent like $$H_2 O$$ while covalent bond does not. · 7 months, 3 weeks ago
