Question

Which one of the following objects is achiral?
A) Letter P
B) Letter F
C) Ball
D) A pair of hand

Answer 1

Stereoisomers are isomers that differ in atom spatial arrangement rather than atomic connection order. Mirror-image stereoisomers, a non-superimposable set of two molecules that are mirror images of one another, are one of their most fascinating types of isomers. The concept of chirality determines the existence of these compounds.

Complete answer: Chiral is the exact opposite of achiral. Achiral objects and their mirror representations can be superimposed. Two pieces of paper, for example, are achiral. Chiral molecules, on the other hand, are non superimposable mirror images of each other, just like our hands.
The term "achiral" refers to any item that is invariant (i.e., superimposable) with its mirror image, which is most typically a molecule, a two-dimensional crystal surface, or a three-dimensional crystal structure in astrobiology. Achiral objects have a symmetry plane, which can be a mirror or a glide plane symmetry operator. A soccer ball, a pencil, and the letter "X" are examples of achiral things, whereas chiral things include a snail shell, your left hand, and the letter "R." In contrast to chiral biomolecular species like alanine and ribose, common achiral compounds include ${H_2}O,{\text{ }}C{H_4},$ and $N{H_3}.$
Because objects and their mirror images are non-super imposable, a ball is achiral while other objects are chiral.
Hence, the correct option is: (C) Ball

Note:
No molecule with diverse surrounding atoms is achiral by definition. Chirality is a simple but important notion that underpins the concept of stereoisomerism and is used to explain one sort of stereoisomerism. The chiral molecule's chemical properties differ from those of its mirror copy, and this is where the significance of chirality in modern organic chemistry lies.
