1. what is product of following reaction CH2===CHCH2CH3 +-------->?

2 What is reaction called if a alkene produces an alcohol?

3 How is alcohol metabolized in liver (what process)?

4 How many stereoisomers does C4H9Cl have?

[macman104]

1)  Uh...you need to give us a reaction.  Is the "===" supposed to be one double bond?

2 & 3)  These are both very simple google searches

4)  Can you try taking a guess at this one?  What is a stereoisomer?

[sanchenuss]

Not trying to be rude but if they are so simple then why can no one here answer them? I thought this was a forum that explained answers that you don't know. I have tried to answer these and cant. Yes the = is one double bond.

im almost sure that 2 is hydration

Correct, 2 is hydration.  Well done! 

We can answer them.  However, we teach through a process of helping point you to the right answers, instead of just handing you the answers.  This way when you are presented with a similar problem, you can reason the answer.

1)  You still need to provide me with the rest of the reaction.  Right now, I have CH₂=CHCH₂CH₃ + ________ ----->.
You need something to react with the alkene...

2)  Info

3)  Scrol down to the section labeled "Metabolic Process"

4)  Do you have a structure for C₄H₉Cl, or is it just the formula?  Does the question ask for stereoisomer or structural isomer?

[sanchenuss]

it is just the forumla, it is asked exactly like "How many stereoisomers does C4H9Cl have?

for the metabolism of alcohol in the liver im almost certain that the answer is oxidation. I will read your link after this post. I have a few more problems that I have worked out and would like to know what you think.

1) Four steroisomers of threonine are named D-threonine, L-threonine, Dallofthreonin and L-allothreonine. The compounds D-Threonine and L-allothreonine are what

a) racemic mixture b) diastereomers c) enantiomers d) meso compounds

The answer that I came up with was b) diastereomers.

2) All enzyme molecules are ?
a) achiral b) enantiomers c) chiral d) superimposable

for this answer I chose b) enantiomers.

3) In first step of the body's metabolism of ethyl alcohol, what forms?

I was scanning my book and the conclusion that I came up with was an aldehyde because I believe carboxylic acid is the second step, another option was alkene and ether.

and for the first question I asked, my book asks for the product of
CH2=CHCH2CH3 + H2 --------->  ?   

where the question mark is there are a list of options for the answers.

Interesting...there are various *structural* isomers of that compound, and some of those may have stereoisomer, but that doesn't seem to be like what they are looking for.  Look at the picture on the wikipedia page for Isomer to see the hierarchy of isomer classification.  I'm not sure of the best way to answer this question.  It's not very clear.

for the metabolism of alcohol in the liver im almost certain that the answer is oxidation. I will read your link after this post. I have a few more problems that I have worked out and would like to know what you think.

Indeed it is oxidation.

1) Four steroisomers of threonine are named D-threonine, L-threonine, Dallofthreonin and L-allothreonine. The compounds D-Threonine and L-allothreonine are what

a) racemic mixture b) diastereomers c) enantiomers d) meso compounds

The answer that I came up with was b) diastereomers.

I can't find all of the structures online in my quick search, but based on the names, etc, it sounds correct.

2) All enzyme molecules are ?
a) achiral b) enantiomers c) chiral d) superimposable

for this answer I chose b) enantiomers.

Not quite.  You don't always have enantiomers of enzymes.  You're on the right track though.

3) In first step of the body's metabolism of ethyl alcohol, what forms?

I was scanning my book and the conclusion that I came up with was an aldehyde because I believe carboxylic acid is the second step, another option was alkene and ether.

Correct, aldehyde.

Ah, we were missing the H2 before.  This is a very standard alkene reaction.  Check out the following link, let me know if you have questions about the information presented there.

the answer that I came up with for how many steroisomers does C4H9Cl have, i came up with two (R,S).

The only other answer I would choose for all enzymes molecules being what is superimposable.

After going through the link, the following reaction I came up with for the product is CH3CH2CH2CH3

[macman104]

the answer that I came up with for how many steroisomers does C4H9Cl have, i came up with two (R,S).

Yea, I mean, I guess that works, it's just not a very clear question.  If the formula is CH3CH2CH2CH2Cl, then there are no stereoisomers, because the molecule is not chiral.  So....yea

The only other answer I would choose for all enzymes molecules being what is superimposable.

What about chiral?

After going through the link, the following reaction I came up with for the product is CH3CH2CH2CH3

Indeed, well done.

[sanchenuss]

chiral? hmmm. I never thought of that one. How does that work? I really appreciate the direction youve given me, if youre up for it, I have just a few more answers that I would like to compare with you.
