It depends which side of the arrow C6H1206 is located on in the equation. If it is located on the left it is a reactant. If it is located on the right is a product.
orientation of incoming Nitro group is destined by already present group on benzene ring . if already present group is electron donating group, it will promote electron density at ortho and para position and , therefore, nitro group is formed on ortho and para position.
First you need to understand what milk is, other than a just a white liquid you get from mammary glands. Milk is an emulsion of fat, water, lactose (a type of sugar) and a mixture of proteins (loads of other stuff, but these are what we will talk about). The small fat globules are surrounded by a...
because without it you wouldn't have any cells and DNA cannot be made without a special protein used to copy it
beacause of n to pi antibonding tranition.
hey .. well its difficult to answer this question as we don't know the conformation of the molecule, but i will admit that you ment a linear molecule having a triple bond between the fourth and fifth C-atom.1-trichlor 4,5 hexin (important is the -in ending. it stands for the triple bond between the...
these are, alkane, alkene and alkyne having single , double and triple C to C bond respectively.
it's exothermic process, in case of complete combution whic occurs in excess air/O2 , products are CO2, H2O, heat. incomplete combustion results in production of CO, C_black, H2O, heat.
yes, it also depends on T.

it is called the sodium monooxide but it is unstable as oxygen has -2 valency and sodium has +1
The difference between silicone oil and mineral oil are its structure and uses. Silicone oil is an oil made of semi-inorganic polymers. It is used in things like lubricants, adhesives, synthetic rubber and electrical insulation. It is also one of main ingredients in Silly Putty. Mineral oil...
Williamson synthesis reaction.
It is dependent on concentration and operational parameter such as temperature. Generally we can say that it increase with increasing the concentration of acetic acid.
is the sugar formed when two monosacharides (simple sugars) are joinedby g lycosdic linkage. Like monosaccharides, disaccharides areoluble in water. Three common examples are ucrose, l actose, and m altose.

Successive amounts of crystals obtained in the second crop are often less pure than the first crop since concentrating the filtrate solution will make some impurities to precipitate with the desired product.
The less the polarity of the compound, the greater its interaction with the mobile solvent so it moves up the TLC plate further.

Alcohols have a slight tendency to lose the proton on the alcohol group, however less so than water, and so they do not significantly change the pH when added to water. They can however be deprotonated by a very strong base. See the Web Links and Related Questions to the left for more information

It's UNUNPENTIUM.The basis is: you want the name for 115 at. no.....so the following letters are used to depict no.'s1----> un5----> pentsuffix----->ium.....as you want it for the element with no's 1..1...and 5..2 times one and 1 time five with the suffix makes it UN+UN+PENT+IUM=UNUNPENTIUM
Acetone has various functions. It can be used as a powerful solvent for cleaning beakers, desks etc. It can have dry ice added to it in order to cool a reaction down to approx -70 degrees centigrade. It can be used as a solvent in some synthesis or as a reagent its self.
repeated extraction in wich solvent is used in small portion are more effective than using a single large volume of solvent
