Organic Chemistry: Sn2 Reactions - proposing a synthesis

AI Thread Summary
The discussion focuses on proposing syntheses starting from 1-butene to create various compounds, including 2-chlorobutane and 2-methoxybutane. A key question raised is how to handle the double bond in an SN2 reaction, which was not covered in class. Participants suggest revisiting the principles of substitution and addition reactions, as many of the desired transformations may require addition rather than substitution. The complexity of the synthesis is acknowledged, with multiple steps and compounds involved in the process. Understanding these fundamental concepts is essential for successfully navigating the proposed syntheses.

Homework Statement

Propose a given synthesis of each of the following compounds starting with 1-butene
a) 2-chlorobutane
b) 2-methoxybutane
c) 2-butanamine
d) 2-butene (mixture of cis and trans)
e) butane

The attempt at a solution
I have the structures for 1-butene, as well as each of the desired products. My question.. how do you deal with a double bond in an Sn2 reaction? This is not something we covered in class, and I have absolutely no idea. I have the answers available, so I'm genuinely trying to understand this; I'm not just trying to simply get the right answers to hand in for homework.

The next question involves just single bonds, going from 2-butanol to all of the above compounds. I'm kind of in the same boat with those, and the answer key makes it seem like there are multiple steps to each one and multiple compounds added. I'm totally scratching my head at this.

I really think you should go back to the drawing board and re-understand the principles of substitution and addition. In addition to the site that @Ygggdrasil mentioned, you could also look at the following site : http://www.chemguide.co.uk/mechmenu.html#top
 
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
