I know that a double bond has the two atoms closer to each other than a single bond. I have to build an organic acid model for chemistry and would like to know:
- Is there a ratio between the lengths of C-C bonds to C=C bonds?
- Are C-H bonds closer together than C-C bonds?
- Are C=O bonds...
does any1 know where i can get a spider diagram for as level chemisry, like the reactions between different organic groups and suchlike
thank you :biggrin: :smile:
organic chemistry help!
how do i name a pentane with a double bond on one end and triple bond on the other end?
pent-1-ene-4-yne?
if an octane has a double bond on one carbon and a phenyl group on another carbon . which should i start with first, the phenyl or the double bond?
I have been searching like crazy for different and easier material on organic chemistry for higher level students on the net, but it's hard to find. I assume that there are knowledgeable participants on this part of the PF and I would like to ask if someone knows of a good link? :smile...
Hi all
I am doing this lab in my organic course right now, and I have a few questions. The phenol I am working on is pKa of p-chlorophenol.
I obtained a UV spectrum of phenol in acid, phenol in base, phenol in buffer with higher pH and phenol in buffer with lower pH.
1)In the UV spectrum...
Isolating caffeine from tea leafs is an experiment in our lab. The manual asks us to determine the percent yield of caffeine by comparing the pure product of caffeine versus the original mass of the tea leafs. My question is, how valid is this method for finding percent yield? I do not...
Hi
I have a few questions in organic chemistry. I would be very grateful if someone can answer them:
1. (cf Morrison & Boyd 6th ed page 523). "Strongly activating groups generally win out over deactivating or weakly activating groups."
When the bromination of 3-hydroxybenzaldehyde...
I find it extremely tough to remember the correct mechanisms and apply them, there seems to be so many different structures etc.
Can anyone offer any advice regarding learning organic chemistry? Are there any decent websites/material which lay out organic chemistry in a more accessible manner...
Hi everyone. I need help with some organic chemistry. When I see a reaction, how do I tell whether it is SN1, SN2, E1, or E2? Also, what is it about a nucleophile that makes it good or bad? Thanks in advance.
Hi there! This is my first post here, so a short introduction: my name is Rui Monteiro and i´m a Chemical Engineering student in Portugal, i´m 19. (btw, anyone from Portugal?)
So, what brings me here:
I came up with this Organic Chemistry Database (with a few inorganic compounds there too)...
