Viscosity of a liquid arises due to strong intermolecular forces existing between the molecules. Stronger the intermolecular forces, greater is the viscosity. Name the intermolecular forces existing in the following liquids and arrange them in the increasing order of their viscosities. Also give reason for the assigned order in one line.
water, hexane `(CH_(3)CH_(2)CH_(2)CH_(2)CH_(2)CH_(3))`, glycernine `(CH_(2)OHCH(OH)CH_(2)OH)`

Explanation

To solve the question regarding the viscosity of the given liquids (water, hexane, and glycerin), we will follow these steps:

### Step 1: Identify the Intermolecular Forces
- **Water (H₂O)**: Water molecules exhibit strong hydrogen bonding due to the presence of highly electronegative oxygen atoms bonded to hydrogen.
- **Hexane (C₆H₁₄)**: Hexane is a non-polar molecule, and the primary intermolecular forces present are London dispersion forces, which are relatively weak.
- **Glycerin (C₃H₈O₃)**: Glycerin contains three hydroxyl (OH) groups, which enable it to form strong hydrogen bonds, similar to water but with more potential bonding sites.

### Step 2: Arranging the Liquids in Increasing Order of Viscosity
