i saw  this  my concepts were cleared hope yours to

Explanation:

/n chemistry, a molecule or ion is called chiral (/kaɪˈræl/) if it cannot be superposed on its mirror image by any combination of rotations and translations. This geometric property is called chirality.[1][2][3][4] The terms are derived from Ancient Greek χείρ (cheir), meaning "hand"; which is the canonical example of an object with this property.

A chiral molecule or ion exists in two stereoisomers that are mirror images of each other, called enantiomers; they are often distinguished as either "right-handed" or "left-handed" by their absolute configuration or some other criterion. The two enantiomers have the same chemical properties, except when reacting with other chiral compounds. They also have the same physical properties, except that they often have opposite optical activities. A homogeneous mixture of the two enantiomers in equal parts is said to be racemic, and it usually differs chemically and physically from the pure enantiomers.

A chiral molecule or ion must have at least one chiral center or stereocenter.[dubious – discuss] When that center coincides with an atom, the substance is said to have point chirality. In chiral organic compounds, a stereocenter is often an asymmetric carbon. Multiple stereocenters may give rise to additional stereoisomers. On the other hand, a molecule with an even number of stereocenters may have one or more stereoisomers which are not chiral.

Chirality is an important concept for stereochemistry and biochemistry. Most substances relevant to biology are chiral, such as carbohydrates (sugars, starch, and cellulose), the amino acids that are the building blocks of proteins, and the nucleic acids. In living organisms, one typically finds only one of the two enantiomers or a chiral compound. For that reason, organisms that consume a chiral compound usually can metabolize only one of its enantiomers. For the same reason, the two enantiomers of a chiral pharmaceutical usually have vastly different potencies and/or effects.

Answer 2

Answer:

• carbon that binds 4 different groups or has 4 different groups attached to it is called “Asymmetric Carbon”
• Chiral carbon is the carbon atom about which all the 4 groups are different..

✷ so by this we can say that to be chiral it must be assymetrical...

1. A compound is said to be chiral if it exist in 2 stereomeric forms which are non superimposable mirror images of each other...i.e;they must be assymetric
2. this property of non superimposablity is called chirality...
3. two compound which are non superimposable mirror images of each other are called enantiomers...

✷eg:

butan-2-ol is a chiral compound bcz it exist in 2 sterioisomeres which are non-superimposable mirror images of each other.....

hope this helps u ✌️☺️
