Hi Guys!  I'm still an O-chem student and i'm having a problem in drawing this compound:

1-(2-methylcyclopropyl)propyne

i can't seem to draw it right..can anyone help me with this?  thanks in advance.

Mod Edit: actual useful title

Show what you did so far, even if it is wrong.

[dubz]

that's what i've done using ChemSketch but it gives a different name..

[discodermolide]

The name you gave suggests that propyne is the parent chain.
So start there.

[dubz]

well, that's what i did but Chemsketch program named it otherwise..

[discodermolide]

Starting with propyne see where you can add the cyclopropylmethyl group.

[dubz]

well i did some more variations but still nothing..take a look





i don't know what's my mistake

[discodermolide]

The second structure is correct.
In the first one you attached the cyclopropylmethyl group to the wrong carbon atom.


1-methyl-2-(prop-1-yn-1-yl)cyclopropane

[dubz]

but i was looking for 1-(2-methylcyclopropyl)propyne ..Chem Sketch gave me a different one..are they the same?

[discodermolide]

Yes they are the same. These are from ChemDraw.

[dubz]

okay, thanks a lot man..still need to study more about this stuff. gonna post some more questions soon

[discodermolide]

No problem
