What effect does a chromophore have on benzene?
It might be that benzene, a non-polar hydrocarbon solvent, will have an effect on a chromophore. A chromophore is, generally speaking, the portion of a molecule that affects the way it absorbs and reflects light, thereby giving it color. Benzne, C6H6, might react with the chromophore to alter it and change the color of a substance, but the substance would have to be specified before any attempt was made to predict the affects of benzene on its color.
What are the differences between resonance effect and inductive effect?
One difference is that inductive effects are based on the electronegativity of an atom and occur through the sigma bond network. The resonance effect donates electrons to the benzene ring and occurs through the pi bond network.
Examples of volatile liquids?
A Volatile liquid is any liquid that can be vaporised quickly. This does not mean they are necessarily flammable. Examples - Water Chloroform Hexane Acetone Petrol methylated spirits alcohol..........
Is there any liquid that ice will not float in?
There are many. The density of solid ice is about 919 kg/cu.m. (kilograms per cubic meter). Ice will sink in any liquid that is less dense than that. Here are a few: * Acetone: 784 * Benzene: 874 * Cyclopentane: 745 * Ethyl alcohol: 789 * Gasoline: 711 * Methanol: 791 * Naptha: 665 * Propane (R-290): 494
In chemistry what is a resonance?
A resonance structure is an alternate way of drawing a Lewis dot structure for a compound. For some molecules, there are multiple ways to draw a Lewis dot structure that still satisfy the rules (for instance, having the correct total electron count and satisfying the octet rule on each atom).Benzene is a classic example where a resonance structure is used. See the Web Links to the left for a diagram of benzene's two resonance structures. Note that in both cases, there are alternating double and single bonds between the six carbons. What changes in the two structures is which bonds are single and which are double bonds. In reality, all the bonds in benzene are identical. They are neither single nor double bonds, but something like a "one-and-a-half bond."There is a common misconception that in reality the molecule is somehow alternating between the two structures. It is not.. This is extremely important to understand! Resonance structures are simply a tool to make up for the fact that Lewis dot structures are not the best tool for describing bonding in molecules (they are very good, just not perfect!). Using resonance structures is a kind of band-aid to patch up this shortcoming of Lewis dot structures (for a better representation of bonding, you must use molecular orbital theory which requires quantum mechanics!).So if the is not alternating between the two structures, what's going on?! In fact the molecule's structure is always the same. The actual bonding the molecule is a mixture of the different resonance structures all the time. To see this, you have to look at the different structures and imagine blending them together to give one single structure which has contributions from each structure. So the bonds in benzene are not going back and forth being single and double bonds. Not at all! Not even really quickly. Instead the bonds are ALWAYS this average bond which is a bit of both single and double.Note also that not all resonance structures contribute equally to what the molecule really looks like. For benzene, there are two structures, and the real molecule is a perfect mixture of both structures, 50% each. However, the are some molecules for which you can draw more than a dozen structures! In this case, you might have one structure that is dominant, and the real molecule's structure is close to that, and the other structures only contribute a little bit. In other words, the real structure is a weighted average of all the different resonance structures, but the weighting for each structure depends on the details of that structure, and some have very little weighting.How do you tell what structures are more important that other ones? Only if the structures are identical by symmetry, like for benzene, do they contribute exactly the same amount. Another way to say this is that if you can convert between two structures just by rotating the drawing around, they are the same by symmetry. However, sometimes they are not the same at all. Here is how you tell. A better resonance structure has the following properties:-- bond is maximized-- formal charges are minimized-- negative formal charges are carried by the most electronegative atomsThere is no way to predict exactly how much each structure will contribute (except when two are equal by symmetry). But you can put them in order based on the three rules above (and they are listed in order of importance).
What is the isolation of benzene?
Separation of benzene from a mixture is isolation of benzene.
What is the standard enthalpy change for the reaction that represents breaking all the bonds in gaseous benzene?
5535kJ is the reaction that represents breaking all the bonds in gaseous benzene C6H6.
How do you convert benzene into propyl benzene?
benzene with 2~chloropropane in presence of aluminiumchloride
What is pH of benzene?
Benzene has not a pH.
What are pros and cons of using benzene?
The pros of benzene is apple and the cons of benzene is banana.
Is benzene a metal?
Benzene is a liquid, not a metal.
What is the molecular formula of benzene triozonide?
Benzene triozonide is the combination of Benzene and triozonide. Benzene is three molecule of each chlorine and hydrogen and the addition of three molecules of ozone creates Benzene triozonide.
The density of benzene at 15 is 0.8787 Calculate the mass of 0.1900 of benzene at this temperature?
The density of benzene at 15 is 0.8787 . Calculate the mass of 0.1800 of benzene at this temperature.
Why is benzene a mixture?
yes benzene is pure substance with chemical formulaC6H6
Which is the upper layer between water and benzene?
Benzene
What separation method do you use to separate benzene from a mixture of benzene and methyl benzene?
since benzene has a very less boiling point , it will evaporate easily if the mixture is heated . Thus we can obtain the vapour and condense it to obtain solid benzene
