alright then, to get any alcohol, if u would want to convert an alkane to an alcohol all u gotto to do is take out 1 hydrogen.
see methane is CH4 do methanal would be CH3OH with 1 H missing
now tht was the molecular formula what about the structural formula
lets say methane: H so methanol would be: H
l l
H- C-H H-C-H
l l
H OH ===>with H replaced with an OH
same with all the other alkanes. for eg ethan (C2H6) then ethanol would be C2H5) OH) with 1 H(hydrogen atom) missing, and the same with its structural formula.
in the name all u got to do is add -ol-. instead of -ane-,
for eg:the -ane- in propane is replaced by -ol- to be propanol
now the isomer, u just have to move the -OH- from the structural formula
eg: butan-1-ol :
H H H H
l l l l
H-C-C-C-C-OH
l l l l
H H H H
Butan-3-ol
H H H H
l l l l
H-C-C-C-C-H
l l l l
H OH H H
Now see the number on the name depends on the the number of carbon (which is 3 here)(counted from the right) u moved the OH. see u moved the OH to the 3rd Carbon(from the right). If it was moved to the 2nd carbon then it would be name butan-2-ol. just place the number between the name and the "ol". u can also count from the left but the numbers change, but be sure tp follow the rules of isomerese where u should not place the OH on the last carbon atom of the structural formula.
ther u go, hope u understand
thukon:
all u have to do is take the number of carbons- for example if there are 6 carbons, then write "HEXAN"
Then, see where the OH functional group is- If its on the 2nd carbon (doesnt really matter what direction u count from, so it could be 2nd or 4th carbon) then write 2
Finally, since its and alcohol, u have to put the suffix -ol.
So we would end up with hexan-2-ol.
IF we have 2 OH groups, for example if theres and OH branching out from the 2nd and 3rd carbon, you have to write Hexan-2,3-diol.
IF the carbons have a double bond between them, then this would be an alkene, so you have to write Hexen-2-ol (the a in hexane is now an e)
SGVaibhav:
Can anyone please solve this organic chemistry question.
thukon:
Here u go.
AHHHH MY REP KEEPS GOING DOWN. WILL THOSE (mind ur vocab)_______ WHO DECREASE REP FOR FUN PLEASE STOP?
AND WILL THE PEOPLE WHO WOULD PROBABLY DECREASE MY REP BECAUSE I JUST SWORE PLEASE GROW UP?
