@SKYGIRL WITHOUT TAKING TWO MOLES OF ETHYL CHLORIDE BUTANE WILL NOT BE FORMED BY THE WURTZ .........................................................................................
.................. I HAVE A DOUBT

ethanol + SOCl2 ---> C-C-Cl
take two moles...
do Wurtz..
butane will form...
now halogenate...
remove halogen..
double bond forms..
again add Br2...
then remove Br2 with NaNH2...
butyne will form..
btw, wat doubt you have.??
we can expand chain by CN substitution but that will add only one C at a time..
so wurtz reaction is best...
ETHANOL....
NOW WE DEHYDEATE TO GET ETHENE....
NOW ADD Br2 or Cl2 watever available [3]
then add NaNH2 .. becomez ethyne.........
now add NaCN .........
ull get
C C- Na+..........
now add ICH2CH3
.......
IT WILL BECOME 1-BUTYNE..........
IF U WANT 2 BUTYNE ADD NaCN as usual and add ICH3 ......
ULL GET PROPYNE .....
NOW ADD NaCN again.....
NOW Na will attach 2 the 1st carbon attom .......
then add ICH3 again ... CH3 will attach itself there ..........
so ull get 2 butyne .......
this way NaCN comes of gr888888 use .......................
wurtz is not dat gud.............
if u wanna go for shorter ways i wud prefer corey house instead of wurtz..........
or i wud prefer organo metallic compounds as well for step up rxns..........
just that i have a grudge against this wurtz guy ........[3]
@sky..
what gaurav probably means is that it requires two moleules to collide and not two moles :)
so even if you take 1 mole of the reactant you will get half a mole of the product :)
oh achha... he meant this...
sry i din understnd then...
now did.... thanx :)
