Which of the following nitrogen-containing compounds is/are chiral at room temperature?

Question

Quizplus · Accepted Answer

Compound II and III are chiral at room temperature because they both have a nitrogen atom with four different substituents. Compound I is not chiral because it has a nitrogen atom with two identical substituents (two hydrogen atoms) and two different substituents (an ethyl group and a methoxy group), which means it has a plane of symmetry. Therefore, the correct answer is D, II and III.
