IUPAC nomenclature for branched substituents (2)

[skateasian]

why is it methylethyl instead of ethylmethyl if it should be in alphabetical order?

[junebuug]

Could the molecule at 8:50 be called:

5-sec-butyl-5-isopropyl-2-meth­ylnonane?

[antraxuran9]

awesome! you explained in 10 mins something that my teacher couldnt in 5 classes!

[3141819]

thanks alot



[ugiswrong]

and at 8:30 how do you use the bis nomenclature?????

[ugiswrong]

I think you made another mistake at 3:01 because on the top you've got a methylpropyl but on the bottom you actually have a methylbutyl, I ain't no orgo student but am following along for fun, lol, so would it be called....*just a stab here*

5,5-bis(1-methylbutyl),(1-meth­ylpropyl)nonane ????

[aarockaway]

sec butyl NOT isobutyl

[SSJkiller]

1 more question, sorry... but is 2-methyl 5-(1-methylethyl)-5-(1-methylp­ropyl) nonane synonymous with 2-methyl 5-isopropyl 5-isobutyl nonane?

[mizzpeekaboo]

@SSJkiller yes, methylethyl is the same as isopropyl

[SSJkiller]

at around 3:40... is n't one of those branches a 1-methyl butyl group while the other is a 1-methyl propyl group?
