Can 1-chlorobutane be prepared from 1-butanol using NaCl and acetone?
Probably not. Cl- is a good nucleophile, but you have to first turn the OH group in 1-butanol into a good leaving group. The easiest way probably is to first react 1-butanol with tosyl chloride to form a tosylate (-OTs) group, which is an excellent leaving group, followed by addition of NaCl.
Why lassaigne's test failure in diaso compound?
Nitrogen is a good leaving group. therefore,the gas is expelled when the compound is heated. no formation of sodium cyanide.
Main constituent of bio gas is?
Methane is the answer, By the destructive distillation of coal, we can obtain coal gas, coal tar and ammonia. Coke is left as a residue. Coal gas contains methane, carbon monoxide and hydrogen. Since all the three are combustible, coal gas is a good fuel with a high calorific value.
What is meant by what is good for an individual is not always good for a population?
Exactly what it says: something that is good for one person may not be good for everyone else, or the group as a whole.
What are the advantages of tornadoes?
Perhaps the only good thing that comes out of tornadoes is that they destroy old vegetation, leaving room for new growth.
Which is a better leaving group cyanide ion or chloride ion?
Cl- is the superior leaving group because halides form the most stable anions. The stability of an anion reflects its ability to bear a negative charge and accept electrons, which is the function of a good leaving group.
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.

Is methane a best fuel?
yes,methane is a good fuel as it does not pollutes environment
Is methane good or bad to the environment?
Generally Bad. Methane is not toxic; however, it is extremely flammable and may form explosive mixtures with air. Methane is violently reactive with oxidizers, halogens, and some halogen-containing compounds. Methane is also an asphyxiant and may displace oxygen in an enclosed space.
Role of concentrated sulfuric acid in sterification reaction?
this activates the oxygen atom of the carboxylic atom which then picks up a proton to form a hydroxyl group, now a good leaving group
Why is methan a good fuel?
methane is a good fuel because itsflammable and non toxic
Why lassaigne's test failure in diaso compound?
Nitrogen is a good leaving group. therefore,the gas is expelled when the compound is heated. no formation of sodium cyanide.
Why do we use methane gas for burning in gas fires?
Methane gas is highly flammable which makes it a good fuel source for gas burning.
What is burning methane?
If you mean is burning methane comparatively better than releasing it into the atmosphere, then yes it is. Methane is a greenhouse gas, twenty-one times more powerful than carbon dioxide. If methane is released into the atmosphere it works as a greenhouse gas. If it is burnt, it released carbon dioxide instead. Carbon dioxide is also a greenhouse gas, but it is not as powerful as methane. So burning methane is good for the environment.
What is good about a landfill site?
It creates methane that can be used to create electricity
Is methane gas bad for the environment?
The gas Methane is not Toxic , however it is highly flammable and can form many explosive mixtures with air. It's violently reactive with oxidizers, halogens, and some halogen-containing compounds. Methane is also an asphyxiant and may displace oxygen in an enclosed space. Asphyxia may result if the oxygen concentration is reduced to below 19.5% by displacement. When structures are built on or near landfills, methane off-gas can penetrate the buildings' interiors and expose occupants to significant levels of methane.
