Why must the spot be applied to the TLC plate above the level of development solvent?5. A Grignard reaction of phenylmagnesium bromide with 3-pentanone gives 3-phenylpentan-3-ol as the major product (we will discuss this reaction later). The crude product contains the3-phenylpentan-3-ol product, unreacted 3-pentanone, and biphenyl (a side product). Adeveloping solvent is found that separates the mixture into three spots on a silica gel TLCplate.Considering the functional groups present, predict which compounds would have thesmallest and largest Rf values. Briefly justify your answer.Temperature (°C)

The objective of this question is to show the functional groups present, predict which compounds…

Concept explainers

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

What's 12,13 and 16?
In the following sub-questions, use your book and notes to generate an argument for each model of light. Remember, on the first day of class we discussed that argumentation requires: ● a claim (which I've given), • evidence (which you should look up in the form of data or scientific principles) and reasoning that connects the evidence to the claim (which you should generate from your understanding so far).
Below are 3 real life situations. Pick two (2) them and explain ALL the science involved in the scenario. This means describe things like what is happening to the gas/liquid/solid molecules or atoms, which principles or laws are at work, why what is happening is happening, and how you know. At sea level, a pot of water will boil at 100 °C. Suppose you wanted to boil the same amount of water high in the Rocky Mountains. What do you expect the temperature will need to be (generally speaking)? Why? A can of soda sits in a sunny spot on the window sill for several hours. It is then opened at the same time as a cold can of soda from the refrigerator. What happens and why? Weather balloons do not float out into space. They reach an altitude of about 15 miles above the surface (3x the height of Mt Everest) and they burst. Why?
