C. Earth's gravitational force is stronger than the Moon's.

Since Earth has a far larger mass than the Moon, its gravitational force is also higher.

Draw all possible Newman projections results from the rotation of C3-C4 bond in 2-methylpentane and label all the conformations.

Elden [556K]

Answer:

See the image Below

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 in front of the other, therefore you rotate the bond by rotating the groups that are bonded to the carbons. i. e. in the 2-Methylpentane (viewing the C3-C4 bond) the carbons chosen are the 3rd and the 4th then you look to which are the other groups bonded; 2 H and an isopropyl for the 3rd one, and 2 H and a Methyl for the 4th one.

The different rotations of those groups receive different names:

Anti Conformation: Main groups of the two Carbons are 180º apart from one another. Making this the most stable conformation of the molecule. (Taking into account steric effects)
Gauche Conformation: 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.
Eclipsed Conformation: The less stable conformation since the main groups are confronted.

How do we determine the central atom in a chemical bond? How information is need to determine the shape that results in the bond

EastWind [94]

Answer:

- the central atom is usually the atom with the lowest subscript in the molecular formula and the atom that can form the most bonds. If all of the atoms usually form the same number of bonds, the least electronegative atom is usually the central atom.

- molecular shape (the shape that a single molecule has) is important in determining how the molecule interacts and reacts with other molecules. Molecular shape also influences the boiling point and melting point of molecules. If all molecules were linear then life as we know it would not exist.
