Question

out of hydrogen bond and covalent bond which is stronger ?

Answer 1

1. Covalent bond is more stronger than a hydrogen bond.
2. This is because,covalent bond is formed by proper sharing of electrons between the two element,and hydrogen bond is the partial polarisation of hydrogen of one element by the electronegative element of another molecule. As shown :

$$\begin{gathered} O-H\cdots O-H\cdots =Hydrogenbond \\ {\delta }^{+}{\delta }^{-}-=Covalentbond \end{gathered}$$
