Which of the following molecules are chiral and which are achiral?

butane

2-butanol
2-propanol
2-bromobutane
1-bromobutane

Answer 1

Addison Armstrong

#"2-butanol"#, and #"2-bromobutane"# are chiral.

#C2# of #"2-butanol"#, and #"2-bromobutane"# have 4 different groups attached, and the compounds are, therefore, capable of supporting optical isomerism, viz. 2 optical isomers. These materials would be extremely hard to resolve experimentally.

To determine whether a molecule is chiral or achiral, we need to assess its symmetry and the presence of a chiral center. A chiral molecule lacks a plane of symmetry and contains at least one chiral center, while an achiral molecule has a plane of symmetry or contains no chiral centers. Without knowing the specific molecules provided, I can't determine their chirality. Please provide the list of molecules for analysis.

Answer from HIX Tutor

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
