Important Topics for JEE MAINS 2016 Chemistry | Scoring Topics

Chemistry is believed to be the best scoring subject for JEE Exam. JEE Main constitute of 30 questions of Chemistry section carrying 4 marks each. In order to qualify for JEE Advanced exam a candidate must clear the cut off marks for each and every subject. JEE Advanced 2015 cut off marks for chemistry is:-

Category Marks
General Equal to or more than 17
OBC Equal to or more than 16
SC Equal to or more than 9
ST Equal to or more than 9
General-Pwd Equal to or more than 9
OBC-Pwd Equal to or more than 9
SC-Pwd Equal to or more than 9
ST-Pwd Equal to or more than 9

It means a candidate who appeared for JEE Mains 2015 exam must have secured at least 17 marks (for general category) to qualify for JEE Advanced exam ignoring the marks of other subjects. JEE Advanced 2016 cut off marks will be almost coherent to the cut off marks of 2015.

In order to help you out I did a complete study about some most important topics for jee mains 2016 chemistry part and have find out the top 10 scoring topics of JEE Mains 2016 chemistry.

These ten topics have three topics which are must for every candidate who want to qualify for JEE Advanced and other seven topics are also scoring. These ten topics are enough to get a good rank in JEE Main exam or one can say that these ten topics are the most important topics for jee mains 2016 chemistry part.

I did some hard work and searched last 10 years questions of AIEEE/JEE Main to find out the number of question asked from each and every particular topic of chemistry so that you can prepare smartly. So here is the list of important topics for jee mains 2016 chemistry.

Important Topics for JEE MAINS 2016 Chemistry:-
