How do you identify structural isomers, geometric isomers and enantiomers from compounds?

Answer 1

By (i) their #"connectivity"#; and (ii), by their #"geometry"#.

Please refer to this previous response. The subject matter is undoubtedly more extensive than what we can cover in a few paragraphs, so feel free to ask again if you have any specific questions.

Structural isomers have the same molecular formula but different structural arrangements of atoms. Geometric isomers have the same connectivity of atoms but differ in the spatial arrangement around a double bond or ring. Enantiomers are non-superimposable mirror images of each other, with identical connectivity of atoms but differing in their spatial arrangement in three dimensions, often around a chiral center.

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.
