'Structural isomers' differ from 'spatial isomers' in terms of:
'Structural isomers' have different connectivity between atoms.
'Carvone' is an example of these types of isomers:
'Optical isomers'
What are structural isomers and spatial isomers?
They have different arrangements of atoms in space.
How do acetic acid and methyl formate differ in terms of their molecular structures?
The arrangement of carbon atoms is different.

Smell
In which type of isomerism are carvone's S-(+)-carvone and R-(−)-carvone categorized?
Optical isomerism
What distinguishes acetic acid from methyl formate?
The arrangement of hydrogen atoms
Which feature causes acetic acid and methyl formate to have different chemical properties?
Arrangement of oxygen atoms
Why would using a solution of methyl formate instead of acetic acid be unsuitable for making salad dressing?
Methyl formate has a different arrangement of atoms.
Which type of isomers are acetic acid and methyl formate examples of?
Structural isomers
'Carvone' compounds have mirror image isomers known as:
Enantiomers
What property makes acetic acid and methyl formate unsuitable for being used interchangeably?
Difference in chemical properties
Describe the difference in the molecular structures of acetic acid and methyl formate.
Acetic acid has one carbon forming a double bond with an oxygen, while methyl formate has an oxygen atom between two carbon atoms.
Explain the concept of isomers using acetic acid and methyl formate as examples.
Isomers are compounds with the same chemical formula but different molecular structures. Acetic acid and methyl formate have the formula C2H4O2 but differ in structure.
How do the smells of S-(+)-carvone and R-(−)-carvone differ?
S-(+)-carvone smells like caraway, while R-(−)-carvone smells like spearmint.
What distinguishes structural isomers from spatial isomers?
Structural isomers differ in how the atoms are connected, while spatial isomers differ in the relative orientations of the atoms in space.
Why would using a solution of methyl formate instead of acetic acid be unsuitable for making salad dressing?
The different molecular structures of the two compounds result in different chemical properties, affecting the taste and safety of the salad dressing.
Differentiate between acetic acid and methyl formate in terms of their molecular structures.
Acetic acid has a C-C single bond and a C=O double bond, while methyl formate has a C-O single bond between two carbon atoms.
Explain the significance of the arrangement of atoms in isomers.
The arrangement of atoms in isomers impacts their chemical properties, despite having the same chemical formula.
Describe the difference in the smell of caraway and spearmint based on the isomers present.
Caraway smells like S-(+)-carvone, while spearmint smells like R-(−)-carvone.
Explain the concept of structural isomers using acetic acid and methyl formate as examples.
Structural isomers have the same chemical formula but differ in how the atoms are connected within the molecules.
Why is it important to understand the distinction between acetic acid and methyl formate in chemical applications?
The different properties of these compounds can have significant effects on their functionality, safety, and effectiveness in various chemical processes.
