PHYSICAL CHEMISTRY
For Std XII, Numericals are of 3 and 4 marks for CET they are 1 Mark. Read the numerical questions properly
- Select the formula from given data and what is asked to calculate
- Sometimes extra information is given like temperature or pressure which is not used in calculations
- See that units are same here as students make mistake and take units as it is for Eg : g and kg or R value in J and w/∆H in kJ
- After substituting values in the formula correctly use log table. 10’s power add at the end
- Students make mistakes in putting decimal point hence learn properly the use of log table from a maths teacher
- We should also know the conversion of units between m↑3, dm↑3, cm↑3, mm etc.
- After calculation write units along with your numerical values
- Remember no units for constants
- You can solve numericals properly provided you know all the formulae along with terms used in formula by heart
- Write logs on one side of the page
- Do not keep numericals from any units as option,some logs of constant remember by heart to save time
- Mole concept is basic ideas for numericals in Std XII Board exam as well as competitive entrance exam
- In XII std exam if time does not permit then atleast write correct formula as it carries some mark
- Along with numericals there are definitions, terms to explain and some derivations which maybe asked for 2 or 3 marks
- Long questions are combining 2 questions or many i.e. sum of all remaining weightage. The long questions is of 7 marks. There is always a break of 7 marks. The questions are labeled diagram (descripTion should include important points)
- Reactions
- Advantages / disadvantages / uses etc
- Measurement of emf of cell / Daniel cell / Dry cell / Fuel cell / Colomel electrode / lead accumulator/ methods to avoid corrosion /applications of emf series etc. can be asked for 4 marks
Chapter-6-General principals and processes of isolation of elements
- Short notes- concentration processes ,Froth floatation, leaching, roasting , calcination, pyro, hydro, electro-metallurgy, refining process, etc
- Many diagrams[no Ellingham diagram]
- Many reactions
- No numericals
Chapter-7-p-block elements
- Trends in physical and chemical properTies of 15, 16, 17,18 groups, anomalous behaviour of first element of each group
- Many reactions
- Many structures- oxides of N, P, S, and interhalogen compounds, PCl3 ,PCl5, oxyacids of P and Cl
- Diagrame- allotrpes of S and P, PCl3, PCl5, IF7
- No numericals

Best of luck for your exams. Do leave a comment below if you have any questions or suggestions.
Thanxx…Sir…I hope these questions will help us in exams.
Please post important questions list of chemistry-II fast for Maharashtra Board.
Hi KV,
Chemistry-II is updated here : https://hsc.co.in/chemistry-ii-science-hsc-important-questions-bank-maharashtra-board-2016/
Will the help us for boards…
Hi Sakshi, it will help you to prepare for your boards. We shall keep on updating more and more of important questions as given by our sources. However please prepare yourself with entire syllabus.

And please make a note that there is no 11th question number…sorry its a small mistake but still…
Hi Sakshi, thanks for your valuable input. We have made the changes accordingly. We would also appreciate your more inputs to make our website more helpful to students.
I suggest to read entire syllabus if 12th thouroughly and hope qs in the respective papers would be asked from the exercises given after each chapter.
hello sir I want to know that how can i make a time table to studies
for from now and effectively i will do my best

on what bases are this importance marked ??
if only this importance are studied , atleast how much marks will be obtained???
Sir u said early that 50% aggregate marks of board should be need for mhcet if we are not getting 50% marks and getting good marks in mhcet than we will get the admission or not
In chemistry important questions. …There are some chapters which have NO NUMERICALS written….what does it mean?…is that we have to skip the numerical of that chapter….plz revert soon….
It’s a fake and waste of time thia website is not helping at all
