Situational Irony

Situational irony is a literary device that you can easily identify in literary works. Simply, it occurs when incongruity appears between expectations of something to happen, and what actually happens instead. Thus, entirely different happens from what audience may be expecting or the final outcome is opposite to what the audience is expecting. It is also known as irony of situations that generally include sharp contrasts and contradictions. The purpose of ironic situations is to allow the readers to make a distinction between appearances and realities, and eventually associate them to the theme of a story. http://literarydevices.net/situational-irony/
