If cis tra(cid:374)s iso(cid:373)ers pre(cid:272)ede the lo(cid:272)ator (cid:374)u(cid:373)(cid:271)ers (cid:449)ith either (cid:862)(cid:272)is(cid:863) or (cid:862)tra(cid:374)s(cid:863) 3. Ide(cid:374)tif(cid:455) a(cid:374)d locate the remaining substituent groups; group together like ones. 4. arrange substituent groups in alphabetical order with proper use of commas and hyphens. 2,4-dimethyl-3-isopropyl-2-heptene cis-5,5, 7,7-tetrachloro-3-octene: find the longest continuous hc chain that contains the triple bond and give the parent name (cid:271)(cid:455) repla(cid:272)i(cid:374)g (cid:862)a(cid:374)e(cid:863) (cid:449)ith (cid:862)(cid:455)(cid:374)e(cid:863) Number the chain to give the triple bond the lowest number and place locator number in front of the parent name. One common name to be aware of hc=ch is called acetylene 39. When working synthesis problems, you must show all possible products and recognize which product would be predominant. Hydrogenation: addition of h2 a (cid:373)etal (cid:272)atal(cid:455)st a(cid:374)d heat or pressure is used to saturate double or triple bonds in alkenes or alkynes: plati(cid:374)u(cid:373) (cid:894)pt(cid:895), (cid:374)i(cid:272)kel (cid:894)ni(cid:895) or palladiu(cid:373) (cid:894)pd(cid:895) is used as a catalyst.
