# In $C_2H_5OH$, which type of hydrogen bond can be observed

$\begin{array}{1 1}(a)\;\text{ Intramolecular hydrogen bond}&(b)\;\text{Intermolecular hydrogen bond}\\(c)\;\text{ Both intra and inter hydrogen bonds}&(d)\;\text{None of the above}\end{array}$

Toolbox:
• Inter- molecular bonding means secondary bonding (hydrogen bond, dipole-dipole interaction and London dispersion forces)....due to the presence of the hydroxyl group ( the OH group), the inter-molecular forces between ethanol molecules are hydrogen bonds.
Intermolecular hydrogen bonds will be formed in alcohols.
Hence (b) is the correct answer
