ORGANIC CHEMISTRY
- The basic of all organic chemistry is knowing the structures and their common and IUPAC name of some basic organic compounds. As in XII quesTion paper there are no structures except give IUPAC name
- There are reacTions if you write formula wrong the reacTion will be wrong.
- 3 Marks quesTion can be asked on 3 method of preparaTion, 3 reacTions, mechanism, resonating structures etc.
- There are some reacTions which are named by names of scientist. They are asked for 2-3 marks, like Saytzef’s rule, Markownikof’s rule, Wurtz reacTion, Stephen reacTion, Gaqermann reacTion, Cannizaro reacTion, Fehlings soluTion, Suzurts reacTions etc.
- Always remember the reagents used in the reacTions for conversion of FuncTional groups.Make a table for reagents and which FuncTional group is tionverted to what.
- For reacTions when you write in XII exam without writing reagents no marks for reacTion. Organic chemistry is full of reacTions there is a instrucTion for writing correct and balanced reacTions wherever necessary.Hence study reacTions by heart and you can remember then only by praticing. So write each reacTion on the paper, don’t study reacTions only by reading.
- Long quesTions for 4 marks in 7 marks quesTion can be asked on SN1 / SN2 mechanism, aldol condensaTion etc.
- The science is to the point only use HSC board book. Write always quesTion number and its sub- quesTions as times due to some printing mistake you may get attempt of quesTion marks.
- QuesTion of 7 marks is always a fusion quesTion.There is no internal opTion.
- If in the quesTion it is written explain, then ½ mark for writtng explanaTion and ½ for writtng reacTion
- MCQ solve only once, if you write answers again 2nd or 3rd time, then that part won’t be corrected and it will be written as repeated.
- Possible isomer of some lower compounds up to 5/6 carbons students should know
- No Gillingham diagram to draw, No big numericals on chemical KineTics (Prob 20, 21,22
- Maltose, cellobiose, starch cellulose, DNA,RNA structures will not be asked
- These are all for understanding its significance
- QuesTion paper will have quesTions on knowledge, understanding, applicaTions and skill along with some HOTS quesTions.
