In writing the condensed formula of hexanal, are those two ways of writing the formula correct?

CH₃CH₂CH₂CH₂CH₂CHO

CHOCH₂CH₂CH₂CH₂CH₃

Thanks.

CHOCH₂CH₂CH₂CH₂CH₃

Thanks.

the first one is correct.

the second one isn't. It makes it look like some kind of "mis-spelled" ether. (Because it looks like the first two carbons are attached via an oxygen atom)

So, does this make the second formula correct? Or, it becomes alcohol in this case?

COHCH₂CH₂CH₂CH₂CH₂CH₃

If you want to put the aldehyde on the LHS you could write OHC-

as in

OHCCH₂CH₂CH₂CH₂CH₂CH₃

SWE you are spending a huge amount of time on nomenclature and writing formula. Why not invest some of this time in studying the acdl website official IUPAC systems.

Bookmark the site.

When you have a problem you can browse through the website untill you find the solution.

Ya but generally we write functional groups at the end ...so it is better to write at the end

Welcome to TSR.

A word of advice/warning... when replying to a thread, first check when the last post was, in this case it was eight years ago.

Not too many people will still have much interest after all this time.
