How many different substituents are required on a carbon atom for it to be chiral?
zheka24 [161]

Four different substituents are required on a carbon atom for it to be chiral.

<h3>What is Chiral Carbons ?</h3>

The carbon atom which is attached with four different types of group of atoms or atoms is called Chiral carbon. Chiral molecules are non superimposable on their mirror images. Chiral carbon is also called asymmetric carbon.

Example:

Br - \underset{H} {\underset{|} {\overset{CH_3}  {\overset{|}{C}}}} - Cl

In the above example we can see that carbon atom has 4 different group attached with it that is Br, Cl, H, CH₃.

Thus from the above conclusion we can say that Four different substituents are required on a carbon atom for it to be chiral.

<u>Chemical Change </u>

A chemical change occurs on the molecular level and produces a new substance. However, a physical change rearranges molecules and does not produce a new substance.

                    <u>10 examples of chemical changes</u>

  • Burning of paper and log of wood
  • Digestion of food
  • Boiling an egg
  • Chemical battery usage
  • Electroplating a metal
  • Baking a cake
  • Milk going sour
  • Various metabolic reactions that take place in the cells
  • Rotting of fruits
  • Decomposition of waste

                      <u> Impacts of Chemical changes</u>

Anytime a new substance is made, a chemical change takes place. Usually two or more materials are combined and a new substance is formed. A chemical change can produce amazing explosions, like fireworks.

Thus, <u>all of the above</u> is the correct answer. Learn more about "Chemical Changes" here

When you blow dry your hair
mixer [17]
In short a physical change is something that changed the way something looks but doesn't affect the chemical makeup. Drying your hair doesn't change the color of your hair, it just makes it dry so thats a physical change. Rust forming on a knife is a chemical change becaause the water reacts with the chemical makeup of the knife. Hope that helps.
