Which of the following compounds is (are)achiral?

Question

Quizplus · Accepted Answer

Compound 1 contains a chiral center due to the presence of four different substituents on the carbon atom - a hydrogen, a bromine, a chlorine, and a methyl group. Therefore, it is chiral.
Compound 2 contains a plane of symmetry, dividing the molecule into two identical halves, and hence it is achiral.
Compound 3 is a linear molecule, which lacks a chiral center, and it is, therefore, achiral. 
Thus, only compounds 2 and 3 are achiral, and the correct answer choice is (C) only 2 and 3.
