.Iodine.Br...CH3
.....|.....|.......|
H.-C...-C....-C..-CH2CH3
.....|.....|.......|
....H....H.....H

最尾個CH2CH3係咪即係:
.H...H
..|....|
-C..-C-H
..|....|
.H...H

咁個名係:2-bromo-1-iodo-3-methylpentane??

咁個名係:2-bromo-1-iodo-3-methylpentane??
係,
首先, 佢個主鏈main chain有5個c,所以係pentane
之後有br, I , CH3 係支鏈, 跟據IUPAC system, a放先,z放後(姐係跟abc先後次序)
所以br先,i之後,methyl再後就正確
以br開始,所以你寫2-bromo-1-Iodo-3-methly係岩ge.

係咪有structural formula,又有condensed structural formula??
如果變做condensed structural formula係點?

.I....Br..CH3.....
.l.....l....l...........
CH2CHCHCHCH3

condense formula 其實姐係將碳單鍵(carbon single bond)的主鏈化做CHx 既樣(但double bond的主鏈就要以=表示, trible bond就三劃) 而支鏈就以其bond ge數目以一劃,二劃,三劃放在主鏈的某個碳上表示
