Isomers AS question

The molecular formula is C4H10O.

1) a) The molecular formula calculated can represent a number of isomers from 2 different homologous series.
Draw:
i) Structural formulae
ii) Skeletal formulae
iii) Displayed formulae
for each of the isomers.

b) Name all of the alcoholic isomers.

I'm so stuck on this question, can someone please explain it to me?

Do you know what an isomer is?
Yeah, it's when they have the same molecular formula but a different displayed formula :smile:

Okay good. I would start by drawing out one isomer, say CH3CH2CH2CH2OH in displayed form. The try moving the functional group around the chain. The start branching the chain. Then change the functional group...

So for structural formula just make sure that it equals c4h10o. 1) CH3CH2CH2CH2O (Double check this) and 2)CH3CH2(CH3)CH2O

Skeletal formula = /\/\o and o/\/\ the line with the o = the double bond.
So for the displayed formula just place the Oxygen at the opposite C end.

Hope this helps :smile:
