1koi na :P
these r the question i faced in bitsat 2009 on yesterday
1. wat is EDTA
A hexadentate ligand
B bidentate ,,
C tetradentate ,,
D pentadetate ,,
i mark A
2.wat is the denticity of oxalate
A hexadentate
B bidentate
C tetradentate
D pentadetate
i mark B
3. which is true for [Ni(CN)4]2-
A sq. planar & paramagnetic

hey solve this dy/dx = sin(x+y)
i forget the option but i think which i had marked was tan(x+y)-sec(x+y)=x+c i dont give sureity
i was given 4 quest. on differential equation
1but EDTA can behave as tetra dentate too but generally we take hexadentate so i too..
1at tat time i differentiated the first option & got the answer see some more quest. in calculus section
1take x+y=t....
and then find dy/dx in terms of dt/dx....and then integrate....
1yaar how many questions were there in english and logical reasoning part and how was maths and physics....
1EDTA IS HEXADENTATE....................ANS. FOR FIRST ONE IS [A]
1how many questions were there in english and logical reasoning part....
1i got 356 according to bitsat but i think i will get 5 marks more becoz i told one wrong question and math was easy and physics, chemistry too 4-5 question were came from past iit question but english was very tough and logical was tough and they made me to come down from 400
