Question

Draw the structure for cis-2,3-dibromo-2-hexene.

Answer 1

it does get messed up

oh well.

DO your skeleton 6 legs on the second from right to left your right facing computer put double bond

first and last carbon has h3
left carbons 4,5 have h2 and carbon 2, 3 have br facing each other. IF you put them one up and one down you will create trans.

Answer 2

We can't draw structures on the board; however, this may help.
C-C=C-C-C-C
Start counting from the left. On carbon 2 place a Br atom. On carbon 3 place another Br atom ON THE SAME SIDE (place the Br atoms both on top or both on bottom). That is the cis form. Fill for a valence of 4 on the other carbons with H atoms.

Answer 3

cis-2,3-dibromo-2-hexene
