(a) Soda can

(b)Screwdriver

(c)Screw

(d)Shoe

Short Answer

Expert verified

Answer

(a) Soda can is achiral.

(b) Screwdriver is chiral.

(c) Screw is chiral.

(d) Shoe is chiral.

Step by step solution

01

About chirality

An object is said to be chiral if it is non-superimposable on its mirror images. The mirror images are not identical to each other.

02

About the chirality of soda can

(a) The mirror images of soda cans are superimposable on one another. So it is an achiral object.

03

About the chirality of the screwdriver

(b) The mirror images of the screwdriver are not superimposable on one another. So it is a chiral object.

04

About the chirality of screw

(c) The mirror images of the screw are not superimposable on one another. So, it is classified as a chiral object.

05

About the chirality of shoe

(d) One shoe is not superimposable on another shoe but they are mirror images. So it is a chiral object.
