Smell Unit Test Flashcards
What substances have a smell
Molecular covalent, small and medium polar molecules, and anything in a gas phase
What substances have a smell
Molecular covalent, small and medium polar molecules, and anything in a gas phase
HBr attract a charged wand?
Yes because one is positively charged and the other is negitive
Symmetrical
Has a smell
Asymmetrical
No smell
Molecular formula
The types of atoms, number of atoms, and the arrangement
Bond for HBr
Polar covalent
What does molecular formula tell you about smell
Electronegativaty, polarity, and functional groups
Structural formula
Shows how the atoms are arranged and how many bonds they have (you connect each atom depending on how many bonds an element has)
Covalent bond
Polarity, bond strength, and electron sharing
Ionic bond
Electron transfer, ionic compound, attraction of ions
Polar covalent
Unequal electron sharing, electronegativity difference, charges, and polarity
What does polarity have to do with smell
The solubility and how the receptors lock within your nose
What does size of molecule tell you about smell
Larger the molecule, the more potent the smell
Smell unit = molecules because..
Molecules in the air are more likely to smell because they lock in with nose receptors
