<h3>Explanation</h3>
Replacing an H atom with a Cl atom in a 1,2-dibromoethane molecule produces a molecule of C₂H₃Br₂Cl. Its structural formula is show in the top-left corner of the sketch attached.
The molecule contains no double or triple bonds. It has no E/Z isomers. The two stereoisomers can only be enantiomers. A red asterisk * is placed next to the only <em>chiral</em> carbon in this molecule.
That carbon atom is connected to
- one H atom,
- one Cl atom,
- one Br atom, and
- the alkyl group CH₂Br.
The two isomers are <em>mirror images </em>about this carbon atom. Indicate how the four groups are arranged in space using the wedge and dash notation.
- Solid lines refer to chemical bonds in the plane of the paper.
- Wedges refer to bonds pointing out of the page towards you.
- Dashes refer to bonds pointing into the page away from you.
The last row of this sketch shows the structure of both isomers. The question is asking for only one. Showing either of them should work.
Answer:
Orange, blue
Explanation:
A way to determine the color of a compound is using the Crystal Field Theory (CFT), which depends on the wavelengths of the electromagnetic spectrum.
The spectrum is formed by different wavelengths, each one with a color. The color happens when the electron is excited, and the goes from a higher level. When it returns to its original energetic level, it releases a photon, in a color way.
So, in CFT, the substance is placed in a light with a mixture of colors. The photon will absorb the color of its wavelength and will reflect the other color, which will be seen in the solution. In this case, the mixed light was prepared with blue and orange colors.
Then, the Cu(H₂O)₆²⁺ ions will absorb the orange color, and reflect the blue one, and the solution will be blue. The beta-carotene will absorb the blue color and will reflect the orange, so the solution will be orange.
"Ions are formed when atoms lose or gain electrons in order to fulfill the octet rule and have full outer valence electron shells. When they lose electrons, they become positively charged and are named cations. When they gain electrons, they are negatively charged and are named anions." -Study.com
The answer is b) Water.
a) and c) options are elements and d) option is a mixture.
It’s because two is four and it was really kind of you and it’s c
