A critical paper, also known as a critical essay or critical analysis paper, is a type of academic writing in which the writer evaluates and analyzes a text or work of literature, often a book, film, or artwork. The goal of a critical paper is to engage with the text or work on a deeper level and provide a nuanced analysis of its themes, symbols, and meanings.

To write a critical paper, the writer must first closely read and analyze the text or work in question. This requires careful attention to detail and a thorough understanding of the text or work's context and background. The writer should consider the author's purpose, the audience for which the text or work was intended, and the historical and cultural context in which it was created.

In addition to analyzing the text or work, a critical paper should also provide a personal interpretation or evaluation of the text or work. This may involve identifying the strengths and weaknesses of the text or work, discussing its implications or relevance to contemporary issues, or offering a unique perspective on its themes or messages.

To support their analysis and evaluation, the writer should also incorporate evidence from the text or work, as well as from other sources such as secondary literature or research. This can help to strengthen the writer's argument and provide a more well-rounded analysis of the text or work.

In terms of structure, a critical paper typically follows a standard essay format, with an introduction, body paragraphs, and a conclusion. In the introduction, the writer should introduce the text or work and provide some background information on its context and significance. The body paragraphs should each focus on a specific aspect of the text or work and provide a detailed analysis of that aspect. The conclusion should summarize the main points of the paper and provide a final evaluation or interpretation of the text or work.

Here is an example of a critical paper sample on the novel "To Kill a Mockingbird" by Harper Lee:

Introduction:

"To Kill a Mockingbird" is a classic novel that explores the complex themes of race, prejudice, and injustice in the Deep South during the 1930s. Written by Harper Lee, the novel tells the story of a young girl, Scout Finch, and her experiences growing up in the small town of Maycomb, Alabama. The novel has been widely praised for its portrayal of the racism and prejudice that were prevalent in the South during this time period, and for its portrayal of Atticus Finch, a lawyer who stands up for justice and equality in the face of adversity.

Body Paragraph 1:

One of the major themes of "To Kill a Mockingbird" is the role of race and prejudice in shaping the lives of the characters. Throughout the novel, Lee uses the character of Tom Robinson, a black man falsely accused of rape, to illustrate the racism and prejudice that were so prevalent in the South during the 1930s. Despite the fact that Tom is clearly innocent, he is unable to get a fair trial because of his race, and he is ultimately found guilty and sentenced to death. This incident serves as a powerful commentary on the deep-seated racism that existed in the South at the time, and the impact it had on the lives of black people.

Body Paragraph 2:

Another important theme in "To Kill a Mockingbird" is the importance of standing up for what is right, even in the face of adversity. This theme is exemplified through the character of Atticus Finch, who serves as a moral compass for the other characters in the novel. Despite facing criticism and hostility from his community, Atticus chooses to defend Tom Robinson in court, even though he knows that doing so will likely be unpopular and may even put his own safety at risk.

Compound 3 is known to be planar 2, although increasing the steric hindrance can in fact result in the two rings being orthogonal 4 3. Placing the NICS probe above the ring centroid on the same face as the axial F atom again generates local magnetic effects. Accessible from amino acids, the thiazolidine derivatives can be synthesized in both enantiomeric forms and with a diverse array of substituents. This low percentage yield could be due to loss of some of the product when transferring the solution from the Erlenmeyer flask to the ice-filled beaker to the Gooch funnel. It was difficult to completely transfer all the solution from one container to another.

Not all of the solid could be transferred from the solution in the beaker to the filter paper. The molecules or ions surrounding the central metal ion are called ligands. Decantation of the reagents from the oil was especially difficult, and a small volume of the oil was accidentally decanted along with reagent solution, resulting in a lower yield. The wire was removed from the test tube. Only the ones who were doing the experiment 50mL of water was placed in the 100mL beaker and heated until boiled. The 12 cm piece of aluminum was placed in the test tube. These can be considered to be attached to the central ion by co-ordinate dative covalent bonds.
