1yes priyam..!! bingo!!
tell y..................

is: a)2 b) 3 c)undefined d)1
2) the rate consant for a first order reaction is equal to the initial rate of reaction wheb the initial concentration of the reactant is:
a) 100 M b) 1x 10^-2 C) 1 M d) 0.1 M
3) the hydrolysis of ethyl acetate was carried out separately with 0.075M HCl and 0.075 M H2SO4. Which of the following relations is correct?
a) k(h2so4) >> k(hcl)
b) k(h2so4) = 2 k(hcl)
c) k(h2so4) < k(hcl)

everywhere smileys and smileys...
less discussions and more smileys [3] [3] [3]
[dun mind.. jus kiddin'........]
13i wud lyk add a ques ....
wat is the molecularity of the rxn ...
Cl2 ->2 Cl
21hey sky answers de do yaar, thn v can soch.
the bawse rule 4 chem
1ans nahi dega yaar iit mein... paper ke saath [2]
isilye thora soch hi lete hai aur 25 days......... [3]
1MATLAB???
ELEMENTARY REACTION IS WHICH ONE ??
IS IT FOR PRODUCTION OF 1 MOLE OF PRODUCT??
THEN ANS SHOULD BE 1.5 ??
Y UNDEFINED??
33Sky... read 12th NCERT.... for molecularity.. it can't be fraction....
1[2]
sorry..........
correct.. forgot that....
well then
two requirements:
1) elementary reaction
2) interger........
[7] [7] [7]
33bcause.. H2SO4 is dehydrating agent....
and Will form little ester again...
21OH!!
is dat Y aswer for 1 is UNDEFINED
KOI explain 3 ka answer pl
13BUT THEN HOW DOES THAT IMPLY THE ANS FOR THIRD IS C \
PLZ ANS MY QUES IN ONE OF THE ABOVE POSTS 2
13BUT THEN Y ISNT SO THAT Cl will cause nucleophilic substitution and wont lead to hydrolysis
and btw conc h2so4 is a dehydrating agent and not dilute
1deepansh Cl- is better leaving group than OEt- .
it cannnot replace it...
33@and btw conc h2so4 is a dehydrating agent and not dilute
agar sher ko akele rakh doge... between sheeps then kya wo ghas khane lagega.... :D
