Question

What is the systematic name for the compound cl3cch2ch2ccch3?

Answer 1

hey .. well its difficult to answer this question as we don't know the conformation of the molecule, but i will admit that you ment a linear molecule having a triple bond between the fourth and fifth C-atom.1-trichlor 4,5 hexin (important is the -in ending. it stands for the triple bond between the two C atoms) but you could also name it the other way around even if it would be less "right" as one has to keep the numbers in the molecule as low as possible.

i hope i was helpful to you. enjoy your organic chemistry
