### Senior Inter Chemistry Study Plan - Solid State, Electro Chemistry and Metallurgy Chapters

Consistency with right strategic plan is the ultimate key to success.
Purposeful planning brings the future into present. A goal without a
plan is just like a dream. Inter marks are as important as entrance
exam marks (or ranks). Have a good grip on 2nd year syllabus, as all
entrance exams will be held at the end of 2nd year.

Solid State:

Most of the times 4 marks question is given from this lesson. For 4
marks Bragg's equation (derivation & problem), calculation of
efficiency of packing in FCC, BCC and simple cubic crystals are
important. As there is possibility of giving two 2 marks questions as
one 4 marks question, it is advisable to read 2 marks questions like
Frenkel & Schottky defects, tetrahedral & octahedral voids, n-type &
p-type semi conductors, crystal lattice & unit cell, problems on
density, f-centres, doping 5 types of magnetism (definitions with
examples) and semi conductor (def.) are important.

For objective exams: 7 crystal systems table, problems on density,
Bragg's equation, packing efficiency, defects in solids,
semiconductors (n & p types) and 2 types of viods. Solutions

One 2 marks, one 4 marks questions will come from this lesson. Before
solving problems in this lesson, one must be perfect in Ist year
lesson Stoichiometry, atomic weights, molecular weights and formulae.

2 Marks: PPm, mole fraction, Henry's law, ideal & isotonic solutions,
osmotic pressure, ebullioscopic & cryoscopic constants, R.L.V.P., In
text questions: 2.2, 2.3, examples. In boxes: 2.1, 2.2. Lesson end
questions:
17, 19, 46, 49.

4 Marks: Raoult's law (def. & problem). In text questions: 2.1, 2.3,
2.5, 2.7, examples. In boxes: 2.4, 2.7, 2.8, 2.9, 2.13. Lesson end
questions: 26, 34, 40, 46, 47.

For objective exams: Van't Hoff factor, Henry's law, Raoult's law,
isotonic solutions, all colligative properties (theory & problems). 2
questions will come in EAMCET and JEE Mains.

Electro Chemistry and Chemical Kinetics:

Every year 10 marks questions (8 M + 2 M or 4 M + 4 M + 2 M) are
coming in I.P.E., 2 questions in EAMCET, 2 to 3 questions in JEE
Mains.
From Electro Chemistry: 2 Marks: In box questions: 3.1, 3.2, 3.3 to
3.7, 3.8, 3.10. In text questions: 3.6, 3.10, 3.12. Chapter end
questions: 1, 4, 5, 6, 8, 13, 14, 23, 31.

4 Marks: Faraday's laws (def. & problems), Kohlrausch's Law (def. &
problems), chapter end questions: 30, 33, 42, 48.

For objective exams: Products of Electrolysis, Lead, storage battery,
Problems on ECell, Conductivity, Kohlrausch's law, Nernst equation,
conductivities- types and ΔG.

From Kinetics: 2 Marks: Chapter end questions: 8, 12, 17, 19, 24, 31, 48, 53.
4 Marks: Order & Molecularity (def., differences, examples of 0th,
1st, 2nd order reactions).
8 Marks: Collision theory, effect of temperature and catalyst on rate
of reaction.
For objective exams: Slope, intercept, problems related to Arrhenius
equation, t1/2, t99% etc, 1st order, rate expression.

Surface Chemistry:

Most easiest topic among 2nd year chemistry lessons. One 4 marks
question is given every year in I.P.E.
4 Marks: Catalysis (definitions, types, examples), Emulsions (types),
examples), micelle & cleaning action of soap, Lyophilic & lyophobic
colloids (def. & differences).

For objective exams: Types of Colloidal systems table, gold number,
flocculation value, Hardy schulze rule, adsorption - types, isotherms
- types, auto catalysis, micelles, +ve & −ve sols examples, Brownian
movement.

General Principles of Metallurgy:

One 2 marks, one 4 marks question are coming every year from this lesson.
2 Marks: Names and formulae of ores of Al, Fe, Cu, Zn, Composition of
alloys Brass, Bronze, German Silver, Uses of Zn, Cu, Fe, Al, Cast
Iron, Wrought Iron, Nickel Steel, Stainless Steel, definitions of
Poling, flux, gangue,
matte, blister copper, slag, ore, mineral, role of depressant in Froth
flotation, role of Si in the extraction of Copper, role of Cryolite in
the
extraction of Al and Zone refining.

4 Marks: Calcination, roasting, Froth flotation, working of blast
furnace, Froth flotation and extraction of Al from Bauxite. Zn from
Zinc blends, Cu from Copper Pyrites. As whole answer for the
extraction of metals is
not given at one place, it is advised to prepare own notes for them.

For objective exams: Formulae of ores, concentration methods of ores,
extraction of metal from concentrated ore, refining methods with
reactions and examples, Zones of blast furnace and reactions,
composition of
alloys.
