Why does fluorenone travel in methylene chloride?
Presumably you are talking about in a chromatography column with alumina in it. The fluorenone is polar and subsequently creates a bond with the polar alumina. However, as Chlorine is more electronegative then the oxygens on alumina, the fluorenone wants to hang out and be friends with the methylene chloride even more than alumina, so the fluorenone and the methylene chloride hold hands and take a romantic walk down the column into your solution.
Why do some compounds travel further on TLC plates than others?
Compounds with lower polarity tend to travel further on TLC plates because they interact less with the stationary phase and are more soluble in the mobile phase. Compounds with higher polarity interact more with the stationary phase, thus travel a shorter distance.
Why polar compounds have less Rf value?
Polar compounds have less Rf (retardation factor) values in chromatography because they interact more strongly with the polar stationary phase, leading to slower movement through the mobile phase. This stronger interaction results in a higher retention time, causing the compound to travel a shorter distance compared to non-polar compounds. As a result, polar compounds have lower Rf values as they exhibit less movement relative to the non-polar compounds in the chromatographic system.
How does an HPLC work to separate and analyze compounds in a sample?
High Performance Liquid Chromatography (HPLC) works by using a liquid solvent to separate compounds in a sample based on their interactions with a stationary phase. The sample is injected into a column where the compounds travel at different speeds, allowing for separation. Detection methods like UV spectroscopy or mass spectrometry are then used to analyze and quantify the separated compounds.
How far do polar molecules travel in thin-layer chromatography (TLC)?
Polar molecules travel a shorter distance in thin-layer chromatography (TLC) compared to non-polar molecules.
How does sound travel farther in cold air compared to warm air?
Sound travels farther in cold air compared to warm air because cold air is denser and has a lower speed of sound, allowing sound waves to propagate more efficiently and with less energy loss.
Is there sound underwater?
Yes, sound can travel underwater, but it travels differently compared to in air. Sound waves travel faster and farther in water due to its higher density, allowing marine animals to communicate and navigate using sound.
How did the building of the railroads affect peoples ability to travel?
People could travel farther and more frequently. Also, rail travel was safer
A cars kinetic energy helps us understand how far it will travel when skidding. If a car travels twice as fast then how much farther will it skid and how much farther if it travels 3 times as fast?
If a car travels twice as fast, it will skid four times farther because kinetic energy increases with the square of speed. If the car travels three times as fast, it will skid nine times farther compared to its initial speed.
Do the Tampa Buccaneers travel farther when they play the Rams in St. Louis or the cowboys in Dallas?
cowboys are farther.
What do sound waves travel farther through?
Solids.
Do the Tampa Bay Buccaneers travel farther when they play Houston Oilers or the Dallas Cowboys?
They travel farther to get to Dallas. Houston is on the eastern side of Texas, closer to Florida.
Will sound travel in water?
Yes, sound can travel in water, but it travels faster and farther in water compared to air because water is denser and transmits sound more efficiently. Sound travels around four times faster in water than in air.
