Chirality and Enantiomers
As you have just seen, the presence of one chirality center in a
molecule causes it to not have a plane of symmetry. Objects that
lack a plane of symmetry are usually chiral. (The only exceptions
are when they possess other symmetry elements such as a center
or axis of symmetry.)
Which of the following molecules are chiral?
1-chlorohexane
2-chlorohexane
3-chlorohexane
1-chloropentane
2-chloropentane
3-chloropentane
