JERIZO:Y did u Modify it Not kul bro |
Re: Organic Chemistry Only!!! by chimhigher(m): 11:43pm On Oct 11, 2014 |
OK GUYS,DROP UR ANSAS SO WE C DOSE DEY GOT DEM ALL ND DOSE DAH GOT SUM.ND WE DO D CORRECTION 2GEDA |
Re: Organic Chemistry Only!!! by JERIZO(m): 11:45pm On Oct 11, 2014 |
To be sincere, I modified it be4 seeing ur comment on my ans. |
Re: Organic Chemistry Only!!! by chimhigher(m): 11:48pm On Oct 11, 2014 |
JERIZO:ok Bro...Let Every1 else DROP DEIR ANSA SO WE C DOSE DAH RE RYT...#URS IS STIL PENDING,WEN ERRY1 IS THRU,I GO KON TELL U HOW MANY U GET..U KUL WT DAHT RYT?? |
Re: Organic Chemistry Only!!! by JERIZO(m): 12:09am On Oct 12, 2014 |
@chimhigher. Are U going 2 give the answer today? I want 2 sleep oh... |
Re: Organic Chemistry Only!!! by Nobody: 12:45am On Oct 12, 2014 |
okay,let me try 1 = 3-ethyl,5-methyl hexane 2 = 2,4,6-trim ethyl heptane 3 = Trans-4,6-dimethyl-2-heptene or trans-4,6-dimethyl hept-2-ene 4 = 3,3,5-trimethyl hexyl-1,6-diamine. |
Re: Organic Chemistry Only!!! by Nobody: 6:47am On Oct 12, 2014 |

Happy Sunday pals. Let's learn a little bit abt representing organic molecules There are a number of ways to representing organic compounds. It is useful to know all of these so that you can recognise a molecule however it is shown. There are three main ways of representing a compound. I would use the example of a molecule called 2-methylpropane to help explain the difference between each. Molecular formula The molecular formula of a compound shows how many atoms of each type are in a molecule. The number of each atom is written as a subscript after the atomic symbol. The molecular formula of 2-methylpropane is: C4H10 Structural formula The structural formula of an organic compound shows every bond between every atom in the molecule. Each bond is represented by a line. The structural formula of 2-methylpropane ( do it on ur own) Condensed structural formula When a compound is represented using its condensed structural formula, each carbon atom and the hydrogen atoms that are bonded directly to it are listed as a molecular formula, followed by a similar molecular formula for the neighbouring carbon atom. Branched groups are shown in brackets after the carbon atom to which they are bonded. The condensed structural formula below shows that in 2-methylpropane, there is a branched chain attached to the second carbon atom of the main chain. You can check this by looking at the structural formula. CH3CH(CH3)CH3 1 Like |

Re: Organic Chemistry Only!!! by Nobody: 8:31pm On Oct 12, 2014 |
It seems people don't really know about skeletal structures here. |

thinezy:i just got admission in unizik to study sci edu,i would lyk 2 knw u beta cus i'm a fresher nd i nid mentors |
Re: Organic Chemistry Only!!! by JERIZO(m): 11:02pm On Oct 12, 2014 |
I have posted my ans. Where are t'he answers to t'he questions? Post t'he correct answer let's know whether we got it right or wrong. |
Re: Organic Chemistry Only!!! by thinezy(f): 7:02am On Oct 13, 2014 |
lucksonlight:oh really ?? congrats!! |

1. 2,4-dimethyl-hexane 2. 2,4,6-trimethyl-heptane 3. 5,6-dimethyl-hept-2-ene 4. 2,4,4,-trimethyl-hexyl-1,6-diamine |
Re: Organic Chemistry Only!!! by Karleb(m): 4:03pm On Oct 13, 2014 |
ikeola6: Yes! infact, I personally do not know anything about it. I've read New School Chemistry, Lamlard Chemistry, Essential Chemistry and one yeye Comprehensive Chemistry like that and yet I've never really come accross the skeletal structure thingy. I guess it's what they teach in Unis, right? BTW, try and explain what skeletal structures means, thanks. |
Re: Organic Chemistry Only!!! by Karleb(m): 4:08pm On Oct 13, 2014 |
beatsbyj2g: Which one is condensed structural formular again? , and why are you not talking about empirical fomula? |
Re: Organic Chemistry Only!!! by Nobody: 4:17pm On Oct 13, 2014 |
Karleb:Well yes and it's taught in pre degree programmes too. They're the simplest to name because each part of the line stands for a carbon atom except a substituent or functional group is attached to it. |
Re: Organic Chemistry Only!!! by beatsbyj2g(m): 5:33pm On Oct 13, 2014 |
Karleb:this are d main ones |
