[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........

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
