Answer: Explanation: In the molecule hydrogen bonding forces tend to resist any phase transition from the liquid state to the gaseous phase, and these hydrogen bonding forces are generally highest when the hydrogen is bonded to a electronegative atom like chlorine, fluorine, oxygen, etc. . 🇧🇷 This reduces the viscosity of the compound.
The least viscous substance is .
More explanation:
Viscosity is defined as the resistance of any liquid to flow. The stronger the intermolecular attractive forces in the liquid, the higher its viscosity.
Intermolecular forces:
The forces that exist between molecules are called intermolecular forces (IMF). They are electrostatic in nature and determine the overall properties of substances, such as melting and boiling points. Molecules are held together in any substance due to these forces.
The different types of intermolecular forces are:
1. Hydrogen bond.
2. Ion-dipole forces.
3. Ion-induced dipole forces.
4. Forces of dispersion
Hydrogen bond: It is an attractive force that exists between hydrogen and the most electronegative elements such as N, O, F. It can be intermolecular or intramolecular. Intermolecular hydrogen bonding is the one that occurs between different molecules. For example, the bond between HF and is an intermolecular hydrogen bond. Intramolecular hydrogen bonding occurs between different parts of the same molecule. Ortho-nitro phenol and salicylaldehyde show this type of binding.
With an increase in the number of fluorine atoms in the compound, the polarity of the compound increases. Due to the increased polarity of the compound, the tendency to form hydrogen bonds with water molecules also increases and this is the reason for the increased viscosity of the compound.
It has the highest number of fluorine atoms among all compounds, so it has a greater tendency to form hydrogen bonds which attributes to its higher viscosity.
it has the fewest number of fluorine atoms of any compound, so it has the least tendency to form hydrogen bonds which he attributes to its lower viscosity.

The substance with the lowest viscosity is ClCHâ‚‚CH2Cl.
The viscosity of a fluid is its resistance to deformation, or it can be defined as the property that opposes the relative motion between two surfaces of the fluid moving at different speeds.
This can be seen from the structure of ClCHâ‚‚CH2Cl, which has a lower viscosity because it has fewer chlorine atoms that can resist movement, so it is less viscous.
