Be sure to look at the charts in the black Merrill chemistry book on page 756 and 761. Ask Mrs. Duncan about the isopropyl, cis,
and trans. Page two of the packet will help you name things. The word Cyclo means that they have to be enclosed.

The charts in the black book are helpful. Make sure to look at both the IUPAC and common names. Page three is one of the most
important pages in the packet so keep up with it. If you are partner two the work goes in the same order as the instructions so it is
easier to do it sections at a time.

The black chemistry book is very helpful. You will use every chart that's in the organic chapter. Pay close attention to alphabetical
order when your naming branches. Don't be scared to ask Mrs. Duncan questions that's the only way I understood any of the
organic problems. Partner 1 you have a lot of book work but it's helpful when you start doing the actual packet. Do the book work

I did the organic labs.
These are fairly simple.
also, record every reaction that you see.
it helped me to read the questions before I did the lab to see what I needed to observe.
the lab report is pretty normal as far as comparison to other lab reports we've done in the past.
also, read the section before the lab. it'll actually answer most of the questions that are in the packet. also helped me with better comprehending the slime experiment.
wish you good luck!
ouida. p.s. learn what VISCOUS means.

The organic labs weren't hard and they were pretty interesting. A lot of the stuff you use is dangerous though so be careful and
make sure to read the directions. Only on the first lab and a part on another do you need to measure exactly so don't waste time
measuring. In the Making Aspirin lab it said to use an ice bath. That is to help speed the cooling process. We didn't do that and it
worked out fine. None of is very difficult. These labs were fun so I think you will enjoy them.

These labs were actually fun because your get to make gluep and slime. Although when you get to the lab that your using sulfuric
acid don't be stupid and get any on your hand. It leaves a scar. Ask Mrs. Duncan questions about cross linking if you don't
understand the concept. Answer the questions as you go and read them before you do your lab so you know what you'll have to
know. Have fun.

This discussion is about the labs. Make sure you do not spill any of the chemicals that you are working with, they are very
dangerous acids. The ice bath on the aspirin lab is just to hurry the cooling process it is not necessary. Be sure to read the packet
and it will help you a lot when you start answering the questions. On the last few labs that you do the measurements do not have to
be exact so don't waste time measuring. None of these labs are hard. You get to make some pretty cool looking things. This is a fun
set of labs.

Definitely do the packet by the sections. It starts out pretty easy, ask Mrs. Duncan to help get you started. The rest of the packet
builds off of the first section so make sure you really understand what you are doing. You will need the chart on page 756 to help
with the third section...the book explains better than the packet.

The book has a lot of example structural formulas that helps you to identify which compound ending name to give, so it’s easy to
look at that if you aren't sure.

The labs are quite interesting to do.
Reading the labs before hand is very important in these labs and you will probably be sometimes lost or have to redo it if you don't.
Be careful even touching the outside of the sulfuric bottle because sometimes people who use it before you aren't careful and can
get it on the outside. If your hands starts to burn while handling it put it down and wash your hands off.

These lab are pretty fun to do. be sure to read the introduction to the labs before you start so you will know what is going on. you
will have to use chemicals in the black hood thing so you will have to work close to it. be very careful with those chemicals.

Remember that carbons have 4 attachments and nitrogens have 3 attachments, as long as you have all your attachments your
drawing should be reasonably correct.
Though the examples in the packet show only changing the -oic ending of the corresponding acid name with the suffix amide,
amides are not always acids, so don't just look for an acid to change to amide.
There are charts in the instruction packet on the last couple of pages that help with naming some of the odd molecular formulas.
Cherish the instruction packet FOREVER!
Organics is not as hard as you think. Just use the packet, it helps out A LOT.

An isopropyl is a carbon with a hydrogen and two methyls off of it with one bond left open. Amines can be named in a large
variety of ways so don't just assume the examples are the only ways.

There is not a melting temperature test, so omit number seven on lab 1.
You may have to wait more than one night for your aspirin to dry.
Use a normal pipet on the second lab.
Use the equation on Page 2 for number 11 on page 4.
Make sure you read before each lab because it helps answer questions in the lab and understand the concepts.
On Part 2 for Lab 3, use 1 molar solutions.
Enjoy:) Marlee Williams
