Identify The Compounds!
A Compound X ,Of Boron Reacts With Ammonia On Heating To Give Another Compound Y Which Is Called
Inorganic Benzene. The Compound X Can Be Prepared By Treating Any Boron Trihalide With Lithium Aluminium
Hydride .
Let "A" Denote The Maximum Number Of Atoms Lying In Same Plane In One Molecule Of X.
Let "B" Stand For Polarity Or Non Polarity Of Compound Y .
If you think that Y is Polar Take Value Of B As 1 .
If You think that Y is non polar take value of B As 2.
Finally
Report The Answer As A+B.
Hint- X Is Used As A Rocket Fuel
The answer is 7.

@Prakhar Bindal – I know. So, let me know if you find out about it's polarity. Also, how much are you getting in today's Phase test ?

@Brahmnoor Singh – I Did Not Got The Mains Answer Key .
But I Feel Some Answers Are Wrong In Advanced Phase Test.with the given answer key i am expecting 480/612 . Do You Have Mains Answer Key?
Log in to reply
@Prakhar Bindal – No, I don't have the Mains Answer Key. And I believe that you are right - there are some questions that I felt had a wrong answer.

@Brahmnoor Singh – How Much Are You Expecting?

@Prakhar Bindal – Peanuts in front of what you are getting...
I am getting just 310 (After making some really stupid mistakes like marking the correct options where incorrect were asked!)

@Brahmnoor Singh – You Are Truely My Brother (I Did The Same Mistake )!

@Prakhar Bindal – :D Glad to know that I am not alone! But I really messed up in Physics. I don't know why - I had attempted the answers with 100% confidence - but the answer key speaks a different story! :P

@Brahmnoor Singh – I Scored Highest In Maths And Lowest In Physics.
I Think In Maths Paper 2 Some Answers Are Wrong

@Prakhar Bindal – Yup, but it's FIITJEE - so I guess there will be no correction!

@Brahmnoor Singh – You are truely my brother! I got Set D too!

It's a website I created. You can post your questions there too! :)

@Brahmnoor Singh – Yeah i registered for it . but till now i have not received the activation mail! .
Log in to reply
@Prakhar Bindal – Sorry Prakhar, I was asleep at that time. The activation email is going in the spam (I know it's a bug, I'll fix it). Check your Spam folder.
@Brahmnoor Singh – I Registered About 30-35 minutes ago (till now i have not received activation mail ) . i clicked on resend activation mail tab too .
@Brahmnoor Singh – What Was Your JEE MAINS Paper Code (If Its Set A Then I Can give you the key) i have set-A Key but i got Set D In Exam
@Brahmnoor Singh – Just doing that question...give me some time. :)
@Brahmnoor Singh – You Should Try This
https://brilliant.org/problems/tricky-problem-9/?group=mzDc02KPvZQC&ref_id=1014917
Its A Very Tricky Problem (Till Now 15 People Have Tried But No One Has Solved It ). Think Twice Before Giving Answer
Clearly Y Is Borazole Or Borazine Which Is Polar . Hence B= 1 .
Now Second Part Is A Very Famous Method Of Preparation Of Diborane .
Hence X Is Diborane In Which 6 Atoms Lie In Same Plane .(The Two Bridging Hydrogens Lie In Perpendicular Plane)
One Interesting Property of diborane is its structure. it actually contains 3 centred 2 electrons bond (also known As BANANA Bonds)
