Sarahisme Posted May 30, 2005 Share Posted May 30, 2005 hey , i can't see why this is called 2-Methylethyl or why it is then called ISOPROPYl if someone has the time, could the please explain this too me ? Thanks Sarah Link to comment Share on other sites More sharing options...
BenSon Posted May 30, 2005 Share Posted May 30, 2005 Is it an Isomer of proane? ~Scott Link to comment Share on other sites More sharing options...
Sarahisme Posted May 30, 2005 Author Share Posted May 30, 2005 ? i'm not sure ? Link to comment Share on other sites More sharing options...
BenSon Posted May 30, 2005 Share Posted May 30, 2005 That disgram confuses me I'm not familiar with that style. is it something like this (add H's) C | C-C Its ethane with an mthyl and also an isomer of propane. What i don't get is the 2 in '2-Methylethyl' does it realy need to be there, I think theres only one position for the methyl and if there was two methyls wouldn't it be dimethylethyl? ~Scott Link to comment Share on other sites More sharing options...
Sarahisme Posted May 30, 2005 Author Share Posted May 30, 2005 yeah i was thinking something like that, but i am 90% sure what i've got is correct....i just don't know why...... :S Link to comment Share on other sites More sharing options...

The correct structure is CH3-CH-CH~~~~ | CH3 so if u look at it;it's pretty simple. Count the no of C atoms and number it from the chain end locating the longest chain of C atoms. You'll see that it has 1C atom at the 2nd position as a substituent. So the name will be 2-methylpropyl(IUPAC) or isopropyl(common name) The isopropyl gp is : CH3-CH- | CH3 Hence the name.

scientistsahai Posted May 30, 2005 Share Posted May 30, 2005 Well the structure is'nt coming as it shud so i'll redraw it CH3 | CH - | CH3 ISOPROPYL GP. Link to comment Share on other sites More sharing options...
BenSon Posted May 30, 2005 Share Posted May 30, 2005 I follow you but it was originally named 2-methylethyl not propyl whats the difference structualy. ~Scott Link to comment Share on other sites More sharing options...

Sarahisme Posted May 30, 2005 Author Share Posted May 30, 2005 Well the structure is'nt coming as it shudso i'll redraw it CH3 | CH - | CH3 ISOPROPYL GP. i see where the "prop" bit is coming from, but do not see where the methyl or "yl" bit is? does "yl" imnply that there is a triple bond somewhere? Link to comment Share on other sites More sharing options...
BenSon Posted May 30, 2005 Share Posted May 30, 2005 I can't find a triple bond here. What i got so far the Isopropyl group is attached to something else on the 2nd carbon in the chain hence the "2". A methyl group it just a CH3 group attacked to a chain and a ethyl group is a CH3CH2 group on a chain. If we add these groups togeher we get, hence methylethyl. CH3 | CH2 | CH3 Here the methyl group is in bold and the ethyl group in italics. Remove a H from the centre carbon (No 2) And it becomes 2-methylethyl. CH3 | CH-R | CH3 ~Scott Link to comment Share on other sites More sharing options...
Sarahisme Posted May 30, 2005 Author Share Posted May 30, 2005 its weird kind of naming then isnt it? i mean its almost a completely different method than how it is normally done.... or at least it seems that way to me Link to comment Share on other sites More sharing options...

BenSon Posted May 30, 2005 Share Posted May 30, 2005 its weird kind of naming then isnt it? i mean its almost a completely different method than how it is normally done.... or at least it seems that way to me Yeah it seems strange to me too but thats the best I can come up with. I find it strange how its name would go into other compounds. example CH3 | CH-OH | CH3 I guess this would be like 2-isopropyl alcohol but couldn't it be called 2-Propanol? Seems like a easyer name to me ~Scott Link to comment Share on other sites More sharing options...
BenSon Posted May 30, 2005 Share Posted May 30, 2005 do guys actually like those kind of breasts? :S They look waaaaaay to fake to me but I'm sure others would prefer them... ~Scott Link to comment Share on other sites More sharing options...
