What are crystalline Give five example
A crystal or crystalline solid is a solid material whose constituents are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. Examples - Diamonds, metals, salts etc.
Answer laterWhat is Mond process .
The process of refining Nickel is called the Mond Process. It is also called the Carbonyl process and is one of the Nickel refining processes. Nickel usually comes in the form of Nickel oxide along with other impurities. A mixture of Hydrogen gas and Carbon monoxide gas is added to the nickel and this process is called syngas. Now the Carbonmonoxide reacts with the impure nickel. Only nickel reacts readily with CO unlike other metals. While the impurities remain solids, Nickel and carbonmonoxide together form Nickel Carbonyl gas. When this Nickel Carbonyl gas is heated, it decomposes to form pure nickel and carbon monoxide.
What happens when aniline is treated with bromine water?
When aniline treated with bromine water, the bromine water gets decolourized and white precipitate is formed. This reaction results in the formation of 2,4,6-tribromo phenylamine. This reaction is an example of bromination.

What is the best way to read chemistry to get above 100 in neet? please suggest some good books too for chemistry...
NCERT most important. NCERT should be on your fingertips. Other than that, for reference, use OP Tandon and MS Chouhan.
Practice previous year questions MANY TIMES . Become perfect in them. Solve other people’s doubts. These will help you score better. You should focus on limited material and do it more number of times !! Many questions ask only basic concepts. Self study is definitely most important. But coaching really helps you score more and you can also appear for a test series and analyse it properly (Giving 2–3 hours), find your strong points and chapters, work on them.
what is nitrogen atomic number
Hello Bhargavi,
As you wanted to know; Nitrogen is the chemical element with the symbol N and atomic number 7.
It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772. It has a mass number 14.057 .
Other important characteristic of it can be described as ; Nitrogen undergoes chemical reaction with itself to form N2.
Hope this helps!
CH3CH2CH2OH + Al2O3/heat -> ?? Mechanism and explanations
This reaction is called dehydration of alcohol and the products usually formed are alkene and water. The products will be CH3CH=CH3 +H2O .
To understand this you have to understand the Saytzeff rule - hydrogen is eliminated from that carbon atom which has less number of hydrogen atoms attached to it. Thus the above reaction proceeds as given.
Mechanism - 1. Attachment of proton to alcoholic oxygen
2. Removal of H2O molecule
3. Removal of proton
As Al2O3 is a strong oxidising agent the reaction mechanism goes in same way as with H2SO4 / Heat.
alpha nepthanol resonance structure
Hi,
The formula is C10H7OH; there are 9 possible ways to draw 1-nepthol resonance structure.
FUTURE STUDY WITH BIO, CHEM,MATH ? I really bad in physics... but,in hs exam i will definitely pass with 40-50 marks i want to know about some carriers guide and future study after 12 with BCM
Dear student
Do not worry about being bad in physics. You need to get atleast 33% marks in each subject to pass in board exams. If you do well in your practical exams and then score 40-50 marks in physics you can pass in physics easily. After 12th you can opt for any couse which does not include physics. Some BSc colleges provide you subject combination options such as ZCB( zoo, chem, botany) ZCM( zoo, chem, maths) etc., You can opt for any of them and make your career. After BSc you get the placement opportunities in the same college sometimes. You can even go for fields other than science such Arts and Commerce ( where you get maths as an option or a major subject). If you are interested in literature related field go for arts. There are various other career options apart from this such as mass communication, computer science, forensics, economics, hotel management, and the list doesn't end. So, relax and focus on your boards first and then choose your field according to your wish. The thing which matters the most is, you should love what you do then only you will succeed in life.
All the best.
what is chemical equilibrium??
.
To understand chemical equilibrium let us understand each of the definition.
.
chemical= An artificial thing prepared for experiment or some other work.
Equilibrium= A state in which forces/influences are balanced.
.
To make understand in simple words, A chemical equilibrium is the point at which concentration of reactants and products doesn't change. It will be seen as the reaction has been stopped but the inner truth is rates of forward and reverse auctions are Equal so they both are been created at the same same.
.
If you are really a chemistry student then you may find this definition useful,
"When the concentration of reactants and products are constant , there ratio doesn't vary"
.
Try to refer an example video of chemical equilibrium from YouTube. You will clearly understand. And you can write in your own words.
Why cocentrated NaoH solution is used in cannizarro s reaction
Hello Sambit
A 50% concentrated NaOH solution is generally used in Cannizaro reaction as it is used for aldehydes which do not have α-H. (There are a few exceptions though) In normal aldol condensation, alpha hydrogens are more acidic so a weaker base can abstract it. But it is not in the case in this reaction that is why a concentrated/stronger base is required.
