Problem: Sort the chemical formulas by chiral versus achiral compounds.H3CCl   PCl2BrCH3+   H2C=CBr2   H3CCHBrCH2CH3   CH2Br2   H3CCHClBr   H2C=CHCH3   HPClBrCH3+

For this problem, we have to sort each chemical formula if they are chiral or achiral:

H₃CCl   PCl₂BrCH₃⁺   H₂C=CBr₂   H₃CCHBrCH₂CH₃   CH₂Br₂   H₃CCHClBr   H₂C=CHCH₃   HPClBrCH₃⁺

• Recall that a stereocenter is an atom that creates stereoisomers after swapping groups. There are two types of stereocenter:

Chiral center: an atom with 4 different substituents
Trigonal center: a double bond capable of forming E/Z isomers
