triple bond structure

Postby martha-1I » Fri Mar 13, 2015 9:02 pm

When drawing the following structure, would we be marked down if we do not draw a straight line down after the triple bond as I did in the second drawing or would the second drawing be accepted as well?

This should have been posted in the Alkynes section. Sorry about that.

Triple bonds are linear since they are sp-hybridized and must be drawn as such. The lines should come out straight from the sides.

Please see the attach file for correct structure. Neither of 1 or 2 is correct. Both the carbon around tb would be linear.
