How hydrogen affects liquid viscosity?
if a liquid has the capability to hydrogen bond then it will be more viscus
How do hydrogen bonds affect the viscosities of propan-1-ol ethane-12-diol and propane-123-triol?
Propane is a gas and has extremely low viscosity. Propan-1-ol has 1 OH group and can hydrogen bond and is higher viscosity. Ethane-1,2-diol has two OH groups and double the tendency to hydrogen bond and is much higher viscosity. Propane-1,2,3-triol is also known as glycerin/glycerol and is almost like a syrup as it has such high viscosity. This is because it has 3 OH groups and thus 3 sites for hydrogen bonding.
Which is a plausible reason for why a given liquid has a high viscosity?
A plausible reason why a given liquid has a high viscosity is that the compound has a high amount of hydrogen bonding. Examples of liquids with a high viscosity are lava, honey and corn syrup.
Why is there a maximum in the plot of viscosity vs mole fraction?
Most likely hydrogen bonding between species in the mixture. This causes large "polymer-like" groupings and increases viscosity
What substance has the lowest viscosity?
Water is the liquid that has the lowest viscosity and helium is the gas that has the lowest viscosity.
What is the order of hydrogen bond strength in various molecules and how does it impact their properties?
Hydrogen bonds are strongest in water, followed by ammonia, and then in alcohols. The strength of hydrogen bonds affects properties such as boiling point, solubility, and viscosity in these molecules.
Boiling point and viscosity of sulfuric acid are high.why?
Sulfuric acid has a high boiling point because of the strong hydrogen bonding between its molecules, which requires a significant amount of energy to break. The viscosity of sulfuric acid is high due to its strong intermolecular forces, which hinder the flow of the liquid.
Why does water have a low viscosity?
Water has a low viscosity because its molecules are small and can easily flow past each other without much resistance. Additionally, water has strong hydrogen bonding which helps keep the molecules connected, reducing friction and viscosity.
How does hydrogen bonding cause viscosity?
It cannot "cause" viscosity, but - Imagine a crowd of peeople waiting for a football match, walking around outside the stadium. Now imagine them loosely holding hands in a random way. The hand-holding is not unlike the effect of h-bonding.
Do you expect the viscosity of glycerol to be larger or smaller than that of 1-propanol?
Glycerol is expected to have a larger viscosity than 1-propanol because glycerol is a larger molecule with more hydrogen bonding sites, leading to stronger intermolecular forces. These stronger interactions result in greater resistance to flow and higher viscosity compared to 1-propanol.
What is the difference between viscosity and viscosity index?
Viscosity is resistance to flow of oil Viscosity Index is a scale to measure viscosity
How does temperature effect the viscosity in honey?
Temperature has a significant impact on the viscosity of honey. As temperature increases, the viscosity of honey decreases, making it more runny and fluid. This is because warm temperatures reduce the hydrogen bonds between the sugar molecules in honey, causing them to flow more easily.
