Senior Inter Chemistry Exam Plan - Weightage for Alkanes and Organic Compounds

Try to answer all the questions by your own, without taking help of the lecturer (after completion of every
lesson).

Halo Alkanes and Halo arenes:

From this lesson, more chances are there for two 2 marks questions from chain isomers of C4H9Br, Conversion of C2H6 to C2H5Br, type of isomerism in O, P, m-chloro Benzenes, Enantiomers, racemic mixture, Sandmeyer's,
Finkelstein, Swarts, Fittig, Wurtz - fittig reactions, why μ of C2H5Cl < Cyclo hexyl Chloride, why aryl halides are less reactive towards nucleophilic substitution, P-Nitro Chlorobenzene & O, P - dinitro chloro benzene undergo nucleophilic substitution readily compared to C6H5Cl, intext questions 11.5, 11.7, Examples in boxes 11.7, 11.9 are important for 2 marks. SN1 and SN2 mechanism is very very important for 4 marks. Organic Compounds Containing C, H, O

8 Marks worth questions are expected from the lesson "Organic Compounds Containing C, H & O". Cannizzaro, Reimer- Tiemann, HVZ, Kolbe's, Stephen, Etard, Gatterman Koch reactions,
Esterification, Williamson's Synthesis, Rosenmund, Wolff- Kishner, Clemmensen Reductions, Aldol & Cross Aldol condensation, Examples in Box: 12.9, Intext Questions 12.1, 12.3, 12.4, 12.16 are very important for 2
marks.

Comparison of Acidic nature between alcohols and phenols, distinguish between 1°, 2°, 3° - alcohols are important for 4 marks. Even in previous years 8 marks questions were asked (2 preparations & 4 Chemical properties) from acetic acid, acetaldehyde. Better to prepare own notes for alcohols, Phenols, ethers, aldehydes, Ketones,
Carboxylic acids separately.

Organic Compounds Containing N

4 Marks worth questions could be given from the lesson "Organic compounds containing N". Better to prepare 2 marks questions like carbyl amine reaction, Sandmeyer's reaction, Gabriel Phthalimide Synthesis, Hoffmamn bromide degradation, Gattermann, Coupling reactions, why aniline does not undergo Fridel - Craft's reactions, why pKb of aniline is more than that of methylamine.
More and more hard work is needed to score maximum marks.
Wish you best of luck!
