Why must the crude alkyl halide product be dried carefully with anhydrous calcium chloride before distillation?
crude alkyl halide in liquid state is too hygroscopic to cath fire even at little temperature! but in solid form its hygroscopic nature lowers decreasing the danger mentioneed above! that's y crude alkyl halide producs should be dried before distillation!
Why must an alkyl halide product be dried carefully with anhydrous calcium chloride before distillation?
My guess is, that any available water can act as a nucleophile and displace the halide producing the alcohol.
Why iron corroded in the presence of ammonium carbamate?
Ammonium carbamate is a chemical salt resulting from the reaction of ammonia and carbon dioxide. The structure is: H2N-C(=O)-O(-)(+)NH4. Ammonium carbamate can be formed without any intermediates by passing ammonia gas over solid carbon dioxide (dry ice). In the real world, there is often water present and this complicates matters. Carbon dioxide and water can react to form carbonic acid, H2CO3. Carbonic acid is a diprotic acid and can react with 2 equivalents of base, so, when carbonic acid reacts with ammonia, ammonium bicarbonate begins to form; HO-C(=O)-O(-)(+)NH4. As more ammonia is added, ammomium carbonate begins to form; H4N(+)(-)O-C(=O)-O(-)(+)NH4. These are equilibrium reactions. As the concentration of ammonium carbonate increases, there is a conversion of some of the ammonium carbonate to ammonium carbamate. This is a dehydration reaction. An industrially important chemical that is derived from ammonia and carbon dioxide is urea, which is used as fertilizer. Urea is ammonium carbonate that has given up two molecules of water; H2N-C(=O)-NH2. The fertilizer plants that manufacture urea have severe corrosion problems due to the ammonium carbamate intermediate. The corrosion is so severe that carbon steel cannot be used. Some parts of the process will corrode 316 stainless steel. Those heated sections are manufactured from special alloys. Why does iron corrode in the presence of ammonium carbamate? Ammomium carbamate is hygroscopic and will attract moisture. Wetted ammonium carbamate will become an equilibrium mixture of ammonium carbamate and ammonium carbonate. This combination of salts and moisture attacks the protective oxide layer on the surface of steel with chelation-type mechanism. This exposes the underlying base metal for further attack.
What is the functional group in propane?
Alkyl
Why are 2 layers of liquid formed in lucas test?
The Lucas test is used to determine the number of alkyl groups present in a compound. It is based on the fact that the compound to be tested is mixed with Lucas reagent, which is a solution of anhydrous zinc chloride in concentrated hydrochloric acid. If the compound has one alkyl group, then a single layer of liquid is formed. If the compound has two alkyl groups, then two layers of liquid are formed.
What is an ammonium carbamate?
An ammonium carbamate is the ammonium salt of carbamic acid - used as a nitrogen fertilizer and in the manufacturer of urea.
Is cypermethrin a carbamate?
No it is a pyrethroid
For what purpose alphamethrin is used?
Alphamethrin is an insecticide that is widely used in India. It is a mixture of carbamate and pyrethroid insecticides that targets aphids and caterpillars.

What are other examples of alkyl halide?
an example of Alkyl halides is R-X ( x represents any halogen) C2F4 is Teflon it is an example of Alkyl Halides

What is the chemical formula of alkyl benzene?
it is C6H5-R , R = any alkyl group.
Which is the contaminant soap alkyl benzene sulfonate or linear alkyl sulfonate?
Depending on the desired definition of the word "contaminant" Alkyl Benzene Sulfonate is more likely the answer. Linear Alkyl Sulfonates are far more readily biodegraded than Alkyl Benzene Sulfonate due to their relative chemical structures. Alkyl Benzene Sulfonate can cause issues in waterways such as eutrophication, which in turn can lead to algal blooms.
The synthetic lubricant presently used with ternary blends containing HCFCs is?
It's alkyl-benzene.
What is the equation of Swarts reaction?
the synthesis of alkyl fluorides by heating an alkyl chloride or alkyl bromide in the presence of a metallic fluoride like AgF, Hg2F2, CoF2 or SbF2.
What is an alkyl phosphate?
An alkyl phosphate is any ester derived from an aliphatic alcohol and phosphoric acid.
What is calcium or compounds of calcium used for?
Calcium is an element, located in group two of the Periodic Table.
