Hey,CO and CO+ Bond length  are 1.128 Angstrom and 1.115 Angstrom .And bond order of CO+ is 3.5 and CO bond  order is 3.So CO+ is more stable bond than CO .But  CO molecule is neutral. in nature.Bond order of CO+ depends on hybridisation of molecule.

Hello ishhika,

Gold is element derived from latin word 'Aurum'. The magnetic ordering of Aurum is diamagnetic.

I hope this helpful for you.

Best wishes!!

Hello!!

Read ncert as many times as you can it has every information required for exams like NEED OR JEE certainly few questions are asked outside the book for those questions solve previous year paper and point questions which ayou are unable to solve write them separately and then memorise them,it is the easiest way to complete everything without reading so many books

Thank you

Hello,

As CBSE ask question from all the three portion of chemistry it is good to prepare all the portion properly to score good marks in exam.

Hello,

To learn and understand any subject, there is only a way to do this is practice. You have to solve 'n' numbers of questions and to do practice. If you find subject difficult then use some tricks which will make it easier for you to understand. If you find it very much difficult to understand then only focus on the important topics which are related with course. Then also if it is difficult for you to cope up with this subject you can leave it and only prepare it for boards not for JEE. You can still get a good score in the JEE with the help of other subjects such as Maths, Organic Chemistry, Physics.

Here are some tips that you can use while learning and practicing this subject

1. Study smartly it means that you do not have to read the whole lengthy answers but to understand it with the help of the practical examples. The examples you can find easily on the internet.

2. Make chart, it means if you want to understand and remember something or some sequence or reactions in this subject you can make a chart of it. So that you can remember lengthy answer or reactions

3. There are various portals which will help you understand the subject. To understand anything there are two ways of it Audio learning and Visual learning and visual learning is the best way of leaning anything. So try to learn through videos with examples. Remember Practice is the key of success.

Hope this answer will help you

Good luck

Hi. Hope you are doing great!

1)physics Concepts of Physics by HC verma

2)for Organic Chemistry Arihant publication

3)Inorganic Chemistry J.D Lee

these are the top reference books for AIIMS.

Hope this will help you!

all the best.

Ayush ;

I get that you want to know about objective questions from chemistry that'll come out of 100 marks in JEE main exam. Considering this , I'd like to suggest that prepare based on NCERT chemistry books.

When it come to inorganic part, almost every single question comes from NCERT books. So, your only virtue of preparation should be NCERT books and don't forget to solve question banks related to inorganic part every once in a while.

Hope this helps!

Hello Roshan,

Hope you are doing well.

Yaa I know this. Even I was confused during my 10+2 years. But what I can guide you by my experience is, go with the book which you are more comfortable with.. Building concepts and clearing topics is much more important than choosing between the books. Every author writes with his own perspective but at the end of the day, concept and things remain the same... Maybe the way of explaining differs that's why I mentioned study from the book that you are more comfortable with.. I had studied it through JD LEE.

Best wishes. Thank you.
