Dear Student,

In Agra local shops the discount may be higher than online purchasing. So in my opinion I am suggesting you to purchase from online shopping. It can be Amazon, Flipkart and others too.

It will take approximately 1000 INR to buy these books in online, with discount.

Thank You.

You can prepare short notes while reading with NCERT. Short notes help you to revise at last min. While making notes you can not forgot any thing. when you are solving sample paper at any point you stuck you can revise with notes. It is easy to learn. While read ncert you can solve sample paper. Solving sample paper will help you to increase accuracy and also help you manage time. It is good if you making notes at the time of reading or learning.

Hi student,

Yes, this time and every time class12 boards exam paper is from NCERT only. Board asks nothing beyond NCERT. Yes, you may get some questions that are not directly asked but directly or indirectly everything is from NCERT only. So, if you want something extra beyond NCERT, then you can check out NCERT Exempler having some higher order thinking skills questions.

Feel free to ask doubts in the Comment Section.

I hope this information helps you.

Good Luck!

Hello candidate,

The formula for calculating out the formal charge of a compound is given by the formula- Formal Charge = [Number of valence electrons on atom] – [number of non-bonded electrons + number of bonds].

Hence, using this formula we get the formal charge on phosphate ion equal to -1, but on experimental basis it comes out to be -.75 because of the involvement of valence electrons in resonance effect other than just chemical bonding .

Hope you found it helpful!
