Document Summary

Therefore, alkynes with the shortest bond length are also the more strongest. For pi bond to occur, ch2"s (cid:373)ust (cid:271)e all i(cid:374) the sa(cid:373)e pla(cid:374)e with o(cid:374)e a(cid:374)other. Half of the pi-bonding orbital is above the sigma bond, and the other half is below the sigma bond. Reminder: cis/trans are structural isomers of each other. If x is present, treat it as an h, if o is present, ignore it, if n is present treat it as 0. 5. Treat each half of the double bond separately and determine highest priority group on each c (recall priority from r+s enantiomers from ch 4) If high priority groups are on the same side: z. If high priority groups are on opposite sides: e. The following is an example from the textbook. For the first example, cl and br are compared as they are both attached to carbon 1 in the double bond.
