Im marking a past paper and the mark scheme says the skeletal formula is 2-methylpropan-1-ol but i didnt put the one. Is it needed and is there a difference between them?
If you don't put the 1 in you don't know where the -OH bond is, which is quite important because if you don't it could be on the first or second carbon. 2-methylpropan-1-ol is more specific.
Hope that helped :)
Thanks for helping. Understand it much more clearly now :)
so long as your oh group is on one of the end carbons of the molecule it is correct
You only put in the number when the functional group is relevant in the naming of the compound.
