Definition of Irony
In Act 1, Part 3, immediately after the scene of Cheveley's confrontation with Robert Chiltern—in which Cheveley initiates her blackmail and the audience learns of the deceitful beginning to Chiltern's career after his sale of insider knowledge of the Suez Canal project—Wilde builds some dramatic irony for the audience by having Lady Markby compliment the Chilterns and their virtues to Cheveley herself:
Lady Markby: Well, dear Mrs. Cheveley, I hope you have enjoyed yourself. Sir Robert is very entertaining, is he not?
Mrs. Cheveley: Most entertaining! I have enjoyed my talk with him immensely.
Lady Markby: He has had a very interesting and brilliant career. And he has married a most admirable wife. Lady Chiltern is a woman of the very highest principles, I am glad to say.
In Act 2, Part 1, Sir Robert Chiltern woefully describes how Baron Arnheim seduced him with talk of power and wealth—talk that ultimately convinced Robert to sell a government secret to Arnheim in order to give momentum to his own political career. With considerable verbal irony, he recounts his experience of Arnheim’s persuasion using the language of philosophy and religion:

I think he saw the effect he had produced on me, for some days afterwards he wrote and asked me to come and see him.
In Act 4, Part 1, Lord Caversham heartily criticizes his son for embodying what Caversham sees as the failings of the younger generation. In a moment of special dramatic irony, he contrasts his son’s behavior with that of Sir Robert Chiltern, who has just given a rousing speech against the Argentine Canal project in Parliament:
Unlock with LitCharts A+Lord Caversham: Do you mean to say you have not read The Times leading article on Robert Chiltern’s career?
Lord Goring: Good heavens! No. What does it say?
Lord Caversham: What should it say, sir? Everything complimentary, of course. Chiltern’s speech last night on this Argentine Canal scheme was one of the finest pieces of oratory ever delivered in the House since Canning.
Lord Goring: Ah! Never heard of Canning. Never wanted to. And did ... did Chiltern uphold the scheme?
Lord Caversham: Uphold it, sir? How little you know him! Why, he denounced it roundly…
