Is an alcohol better leaving group than cyano group?
Although cyano isn't a very good leaving group (it IS a fantastic nucleophile, however), it is still better than an alcohol. The only way you can make an alcohol a good leaving group is to activate it somehow. Methods range from simple protonation (making [H-OH]+ - water) in an acidic environment, to tosyl-/mesylation to make OTs/OMs, to activation with a phosphorous reagent, etc.
Why Alkyl Halides are good for attacked by nucleufile?
This is a really great question that I often drill into my students heads. During the attack of an alkyl halide by a nucleophile, we see the electrons from the Nucleophile emptying into the anti-bonding orbital present at the rear of the carbon atom. It is at this position..... backside.....that the large-lobed anti-bonding orbital is located. This is seen in the SN2 process. In an SN1 process, a carbocation can form,,,,, resulting in an sp2 intermediate....which can readily be attacked by a nucleophile. Halogens such as I- are excellent leaving groups since the anion is stable. F- is a poor leaving group, since the huge negative charge is so concentrated that is results in an unstablized anion.
Is diet DrPepper good for you?
It is better than normal Dr. Pepper but pop isn't good for you.
Is ice a better conductor than copper?
No, Ice is a good insulator and copper is a very good conductor
Who is better in parenting men or women?
It vary according to the man's nature or to the woman's nature. Sometimes a man is better, sometimes a woman is better. Better when both are good parents. Then you are a lucky fellow.
What is the best way to get rid of dog saliva of aniline leather sofa?
It is essential to use a good quality protector on aniline style leathers as this will make this sort of problem much easier to deal with. Aniline style leathers are very absorbent and once stains have been absorbed by the leather they are often impossible to remove successfully. Treating leather with a protector (such as LTT Ultra Protect) will allow the saliva to sit on the surface rather than be soaked in and then it can be cleaned off. Lazy Leather is a unique aniline cleaner which is a non surfactant and will not be soaked up by the leather. It is a great maintenance product for aniline style leathers. source: http://www.LTTleathercare.co.uk

How do you tell if your leather couch is aniline leather?
There are several tests you can do to ascertain this. Moisture test: Put a drop of water on your leather (test in a hidden area first) - don't worry water is good for leather so will not damage it. If the water soaks into the leather and goes dark you have an aniline style leather. If the water sits on the surface you have a coated leather of some sort. Some aniline style leathers will have a finish on them which will slow down the rate of absorption. Scratch Test: Most aniline leathers will scratch with your finger nail and leave a mark These two tests are part of a 5 step process used as an industry standard for testing leather.

What will be the reaction of Hydrogen peroxide with esters?
Peroxide is a good nucleophile, it might be strong enough for an addition-elimination reaction to form a peroxy acid and the alcohol. Depending on the stability of the peroxy acid, it might decompose to the carboxylic acid.
Why protic slovents favours SN2 reaction and aprotic solventsfavours SN1 reactions?
you have it backwards. SN2: you want a polar APROTIC solvent. Protons are bad because they would solvate (surround) and stabilize the nucleophile, making it less reactive. SN1: you want a polar PROTIC solvent. Protons are good because they will solvate (surround) and stabilize the leaving group as it leaves. This lowers the energy of the transition state and makes the reaction go faster. a final teaching point: recognize that your question essentially is about what makes the reaction go faster, which is a question of KINETICS, NOT THERMODYNAMICS (if you want to be good at orgo, this concept is VERY IMPORTANT). You will make the reaction go faster by stabilizing the transition state of the rate limiting step. The transition state of the rate limiting step in an SN1 reaction is the leaving group leaving (the nucleophile is NOT involved, therefore, it does not matter that it is solvated). That of an SN2 reaction is the nucleophile attacking the carbon center as the leaving group is leaving (the nucleophile IS involved, so it must not be solvated).
What is the comparative of good?
Better
Why is anhydrous magnesium sulfate not a good drying agent to dry an ether solution of aniline?
It exists as stable crystals therefore packing fraction is very low and it can not accept the water molecules.

What is an SN2 reaction in organic chemistry?
An SN2 reaction is a one step bimolecular substitution mechanism which is 2nd order in kinetics. An electron rich species (called a nucleophile) attacks an electrophile (electron deficient species) while a leaving group (LG) leaves. Typically a good nucleophile for an SN2 reaction are halides and moderate to strong bases. Good leaving groups are species that are stable on their own like halides, water, tosylate, and protonated ethers. Conditions for an SN2 reaction are similar to the conditions necessary for an E2 elimination reaction; the two are in constant competition.
