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

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]
