Hello.

You can look up the course you have in your 11th and 12th standard, by looking up at the syllabus and what all are included in it. You can find the syllabus on the official website of the board or you can also get it from your school. There you can find what chapters are included in the NCERt book of 11th and 12th standard.

Hi, the chances of you getting a fee waiver is very less. You are likely to get a reputed government College for organic chemistry. Since, the chances of getting fee remembrement you can apply for private scholarships or other scholarships that are provided in your college. If you still have doubts feel free to comment. If you still have doubts feel free to comment. Hope this helps.

Hello Shruti

You should refer to NCERT books first for your preparation make sure you don't skip NCERT book. Most of the questions from Inorganic chemistry is directly from NCERT.

After, completing your NCERT you can refer to OP Tandon

Make sure you refer to previous year papers to get an idea about the type of questions asked in the exam and MCQs for your practice.

It is recommended to focus on the topics which carries more weightage in the exam.

All the best!!

Hello there,

Ores : When the minerals are concetrated or available in sufficient quantity for extracting economically is called an ore.

There are different types of ores like,

• Heamatite
• Magnetite
• Iron Pyrite
• Copper Pyrite
• Siderite etc..,.

There are different methods to extract an ore economically i.e., without loss.

They are,

1. Electrolysis of molten ore
2. Calcination and roasting
3. refining

These metals are extracted based upon their reactivity nature like hight reactivity metals, medium and low.

Please drop a comment if you should have any questions.

Thank You!

Dear Student,

Transition elements are metallic elements that have incomplete d or f shells in the neutral or cationic states. They are called also transition metals and make up 56 of the 103 elements.  Although Sc and Y belong to the d-block, their properties are similar to those of lanthanoids. The chemistry of d-block and f-block elements differs considerably. This chapter describes the properties and chemistry of mainly d-block transition metals.

The period 5 transition metals are yttrium (Y), zirconium (Zr), niobium (Nb), molybdenum (Mo), technetium (Tc), ruthenium (Ru), rhodium (Rh), palladium (Pd), silver (Ag), and cadmium (Cd) .

Dear Student,

The elements in groups 3–12 as shown in the schematic periodic table are defined as the so-called d-block metals. The term transition metal is also often used to describe this group of elements.

The elements which have partially filled d-orbitals either in ground state or in one or more of their ions, are called d-block elements or outer transition elements.

Their properties are intermediate between s-block elements and p-block elements. They are more electropositive than p-block elements but less electropositive than s-block elements.

Dear Student,

The s-block elements are the 14 elements contained within these columns. All of the s-block elements are unified by the fact that their valence electrons (outermost electrons) are in an s orbital. The s orbital is spherical and can be occupied by a maximum of two electrons. Elements in column 1 have one electron in the s orbital, and elements in column 2 (plus helium) have two electrons in the s orbital.

The s-block elements include hydrogen (H), helium (He), lithium (Li), beryllium (Be), sodium (Na), magnesium (Mg), potassium (K), calcium (Ca), rubidium (Rb), strontium (Sr), cesium (Cs), barium (Ba), francium (Fr) and radium (Ra).

Dear Student,

Metallurgy is defined as a process that is used for the extraction of metals in their pure form . Metallurgy deals with the process of purification of metals and the formation of alloys.

Principles of Metallurgy :-

• Crushing and grinding
• The concentration of ores
• Hydrolytic method
• Magnetic separation
• Froth floatation
• Roasting and calcination
