What are these organic molecules names? You have to use FULL nomenclature.
--------------------CH3
---------------------I
a) H2C = CH – C – CH3 – CH3
----------------------I
--------------------CH3
b) H3C – CH – CH2 – CH2 – CH2 – CH2 – Br
---------------I
------------CH3
-----------------------Cl
------------------------I
c) H3C – CH2 – CH – CH2 –CH3
These questions might have been sent wrong.
a) Can you help with this assumption please?
b) You can assume I meant H3C-CH(CH3)-CH2-CH2-CH2-CH2-Br
c) You can assume I meant H3C-CH2-CH(Cl)-CH2-CH3
Did I write the assumptions right?
Please help with the FULL nomenclature for these questions.
The questions on this page were sent right. I meant they might have been sent wrong before.
I think I misinterpreted what you posted; i.e., I mixed up a top question with the upper part of the lower question. I think I understand now what you meant. I think you sent them as you intended. I just didn't read them right.
--------------------CH3
---------------------I
a) H2C = CH – C – CH3 – CH3
----------------------I
--------------------CH3
I would name (a) as 3,3-dimethyl-1-pentene
b) H3C – CH – CH2 – CH2 – CH2 – CH2 – Br
---------------I
------------CH3
I would name (b) as 1-bromo-2-methylhexane
-----------------------Cl
------------------------I
c) H3C – CH2 – CH – CH2 –CH3
I would name (c) as 3-chloropentane

asked by Name them
a) Can you help with the assumption for a please.
H3C-CH(CH3)-CH2-CH2-CH2-CH2-Br can be assumed for b).
H3C-CH2-CH(Cl)-CH2-CH3 can be assumed for c).
I do not know how to write out what to assume for a. Please help.
b) Isn't b 1-bromo-5-methylhexane?
Yes, apparently I can't count, it (b) is 1-bromo-5-methylhexane. Sorry about that. My eyesight is poor but that's not an excuse for not being able to count.
I think (a) is:
.--------------------CH3
---------------------I
a) H2C = CH – C – CH3 – CH3
----------------------I
--------------------CH3
I would name (a) as 3,3-dimethyl-1-pentene.
The CONDENSED FORMULA is as follows.
CH2=CH-C(CH3)2-CH3-CH3
For organic molecules, the full nomenclature involves naming each carbon atom and its attached groups. Let's go through each structure and give them their full names.
a) H2C = CH – C – CH3 – CH3
Start by counting the number of carbon atoms in the main chain: 4. The molecule is a linear chain with a double bond between the first and second carbon atoms.
The full name for this molecule is but-2-ene. The "but-" indicates that there are four carbon atoms in the main chain, and "ene" indicates the presence of a double bond. Finally, we need to specify the substituents attached to the main chain, which in this case are two methyl groups (CH3) attached to the third and fourth carbon atom. So, the full name is 3,4-dimethylbut-2-ene.
b) H3C – CH – CH2 – CH2 – CH2 – CH2 – Br
Again, count the number of carbon atoms in the main chain: 6. This molecule is a linear chain with a bromine atom attached at the end.
The full name for this molecule is hexyl bromide. The "hex-" indicates six carbon atoms in the main chain, and "yl" indicates a single bond on the sixth carbon. Finally, we specify the bromine atom attached to the end, so the full name is 1-bromohexane.
c) H3C – CH2 – CH – CH2 – CH3
In this molecule, count the number of carbon atoms in the main chain: 5. The molecule is a linear chain with a methyl group attached to the second carbon atom.
The full name for this molecule is pentyl propane. The "pent-" indicates five carbon atoms in the main chain, and "yl" indicates a single bond on the fifth carbon. Finally, we specify the methyl group attached to the second carbon atom, so the full name is 2-methylpentane.
Please note that in these organic molecules, the carbon atoms are connected by single bonds unless otherwise indicated (such as the double bond in molecule a). Also, the numbers indicating the positions of the substituents are determined by which carbon atom they are attached to.
