Check the pic attached below and hence find out the basicity order of the following compounds
Explain your answer too.

Look at the attached pic and tell me the order of acidity of the following compounds :
Explain your answer too.

Try out this one :
f(x) =  [log x2 - 1 (x)]
Find the domain of the function.

Sandeep ramesh I have edited my post please check it, instead of copy pasting from Wiki.

explain the use of Ag2O in Arndt Eistert reaction.
I mean i know the reaction mechanism,no need to write that
the use of SOCl2 forming RCOCl, formation of diazoketone using CH2N2,then loss of nitrogen in presence of Ag2O,then Wolff rearrengement......then on hydrolysis it gives the carboxylic acid.
Just tell me why Ag2O is required to remove nitrogen.??

Sorry for the late reply, there was a power cut here
answer given is C

The intervals of decrease and increase of the function f(x) = e^x / x are respectively
( -  , 0 )  ( 0 , 1 ) and ( 1 , )
Then which one is correct ,
a.) p.e^q < q.e^p if 0 < p < q b.) p.e^q > q.e^p if 1 < p < q
c.) q.e^p < p.e^q if o < p < q < 1 d.) q.e^p>p.e^q if 0< q < p < 1

Sorry sandeepramesh I am not a genius like you, so couldnt understand your process.However thanks everybody.Finally i got it.

No answer given is a and b
|
|
|

Another one of the options is correct.

n = 3 ^ 100 then for n
a.) units place is 1 b.) tens digit is 0
c.) units place is 7 d.) tens digit is 2
please dont tell me fermat's theorem and all that please tell me a method using binomial theorem .

Sorry didnt notice ur question
check this diagram this will tell u wat 2 do. when force is applied on the 2nd block.
Similarly for the 7 kg block u can do urself.
|
|
|
|
check the diagram if the force F is > f1 max...then the block a moves with resp to B wid an accn.
where f1 =  1 . 2 . 10 N
