Explanation:
Single C-C bonds have free rotation and thus Newman Projections are quite useful for understanding the different 3D conformations of a molecule.
For any Newman Projection you have 2 bonded carbons, one <em>in front </em>of the other, therefore you rotate the bond by rotating the groups that are bonded to the carbons. i. e. in the 2-Methylpentane <em>(viewing the C3-C4 bond)</em> the carbons chosen are the 3rd and the 4th then you look to which are the other groups bonded; <em>2 H and an isopropyl for the 3rd one, and 2 H and a Methyl for the 4th one</em>.
The different rotations of those groups receive different names:
- <em>Anti Conformation: </em>Main groups of the two Carbons are 180º apart from one another. Making this the most stable conformation of the molecule. <em>(Taking into account steric effects)</em>
- <em>Gauche Conformation: </em>Principal groups are 60º apart from each other. Since are 6 spaces between groups (360º/6)=60º. It is less stable than an Anti conformation due to the same reason.
- <em>Eclipsed Conformation: </em>The less stable conformation since the main groups are confronted.
Answer:
Volume is the amount of space taken up an object.
I think it would be c b then a
Answer:
never true is the answer
explanation:
compounds are formed by two or more elements that are chemically combined with one another. They can be broken down only be chemical or electro chemical means not by physical means.
hence, the answer i have given above is correct
