The increasing chain length of hydrocarbon standards leads to longer retention times due to enhanced van der Waals forces and greater surface area for interactions with the stationary phase in chromatography. Longer hydrocarbon chains have more carbon and hydrogen atoms, increasing their overall hydrophobicity and resulting in stronger interactions with the stationary phase. As a result, these compounds take longer to elute from the column, leading to extended retention times compared to shorter-chain hydrocarbons.

Are there any advantages in increasing retention time?

The retention time would increase becasue longer distance would be travelled by the analyte!


What increases the strength of the hydrophobic interactions in lipid bilayers and thus makes them less permeable to polar molecules?

Increasing the length of the hydrophobic tails in lipid molecules or introducing double bonds in the tails can increase the strength of hydrophobic interactions in lipid bilayers, making them less permeable to polar molecules. Additionally, packing density of lipids and the presence of cholesterol can also enhance hydrophobic interactions and decrease permeability.


What is the lipids that contain the maximum number of carbon and hydrogen possible?

Triglycerides are the lipids that contain the maximum number of carbon and hydrogen possible. They consist of a glycerol molecule and three fatty acid chains, which can vary in length but typically contain long hydrocarbon chains with many carbon and hydrogen atoms.


What does a hydrocarbon chain look like?

A hydrocarbon chain is composed of carbon and hydrogen atoms linked together in a linear structure. It can vary in length and complexity, with simple chains being straight while more complex chains may be branched or cyclic. The general formula for a hydrocarbon chain is CnH2n+2, where n represents the number of carbon atoms in the chain.


Why does viscosity go on increasing with increasing chain length of straight-chain alkanes but for isomeric alkanes viscosity increase with branching?

Viscosity increases with increasing chain length of straight-chain alkanes while that for isomeric alkanes increase with branching because of the difference in the number of rings contained within their hydrocarbons.

How does the flammability of a hydrocarbon change as its carbon length increases?

When the chain length of carbon increase the flammability decrease.


When you increase the length of your workout what are you increasing?

Length is measured in time. So, you are increasing the time of the workout.


Is a short-chain hydrocarbon more viscous than a long chain hydrocarbon?

Typically the shorter the carbon chain, the LESS viscous the hydrocarbon. The longer the chain, the MORE viscous the hydrocarbon. For example consider the viscosity and molecular size in: Gasoline < Diesel < Motor Oil < Tar Viscosity increases with the molecular size and length of hydrocarbon chain.

How is magnifying power of telescope and a microscope are a affected by increasing the focal length of their objectives?

The magnification of a telescope M is the the focal length of the objective Fo over the focal length of the eyepiece Fe so increasing the focal length of the objective increases the magnification. The magnification of a microscope M is approximately tube length L/Fo x 25/Fe. Therefore increasing the focal length of the objective reduces the magnification.

Would increasing the length of a ramp increase mechanical advantage?

Increasing the length of a ramp does not change the mechanical advantage, as mechanical advantage depends on the ratio of the output force to the input force. The length of the ramp affects the distance over which the force is applied, but not the mechanical advantage itself.
