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.
It is true, because a strong magnet that can be turned off and on is an electromagnet.
The formula for beryllium chlorite is Be(ClO2)2.
The beryllium cation has a charge of 2+ and a chlorite ion has a charge of 1-. Using the crisscross method, we move the charge of the beryllium cation to the subscript position of the chlorite ion and the charge of the chlorite ion to the subscript position of the beryllium cation. So, we get Be1(ClO2)2. The ratio one-to-two cannot be reduced further. Since the subscript of Be is 1, we drop it and get Be(ClO2)2.
Answer:
Enery transformation is when a forn of energy changes into another.
Explanation:
An example of this would be a lamp. The lamp gets its energy through electricity. This electricity is later turned into light energy. Electrical energy to light evegy.
