i cant say any thing about 4 and 5

so if you cosider my answer helpful.

plz rate meeeeeeeeeeeeeeeeeeeeeeeeeeee

thank uuuuu

in question 3

the compound A readily converts into B becoz B is most stable than A due to resonance in B.And B will not convert into A. So option C seems to be more correct......

in question 2

i think (a) is correct.
because NO2 group is electron deficient and CH3 group is electron donating so they stabalises the benzene ring..and hence A is more basic than B.

in question 1

you can not judge whether A is more acidic than B and vice versa
because these are two diffrent compounds.....
For comparing you must have some similarity in them ......
so the question will not correct i think...........................

hey man i also want solomons can u provide me the new link
coz the given like doesnt work.......

hi guys and gals!!!!!!!!!1

can anybody provide me the links
to download the following books.......
chemistry----SOLOMONS AND J.D.LEE.
PHYSICS----HALLIDAY RESNIK.
MATHS----K.C.SINHA.

PLZ
RATES ARE SURE....................

it is simple------

it is given that light incident at angle 2A
therefore angle i=2A

and the light incident at 90
so angle r =A

now refractive index = sin2A/sinA
=2sinAcosA/sinA
=2cosA

you cannot integrate logtanx unless you give the limits!!!!!!!!!!!!!

ok?

i also tried it but coudn't succided......

yes i am right the dissosion contant will increase in case of weak electrolytes.

so experts PLZ HAVE A LOOK ON MY ANSWER......................................

dilip i think that concentration of a weak acid such as acetic acid
increases as the concentration increases on dilution(acording to electrochemistry)

so i don,t think that these expert r right in my opinion,
if i am wrong plz correct meeeeeeeeeeee

hey there are rules passed by suprema court
against raging
So, u can complain it in police station.

yes u r right my question is e^x (sin (d/e^x))

i dont know de ans but tell me ur detailed solution

Evaluate:-

lim x tends to 0 (tan inverse x- sin inverse x)/sin cube x

Q:-

lim x tends to 7/2 (2x-9x+8)^[cot(2x-7)]

rates r sure

and the question is

lim x tends to infinity e^x sin (d/e^x)
