Lesson 36/37
This model allows you to see how the various atoms in molecules are arranged in space, as well as the overall shape of each molecule.
What is a Ball-and-stick model?
A double bond only counts as ___ electron domain.
What is "one"?
When the sticks are removed from in between the atoms of a ball-and-stick model, and they are bonded slightly overlapping, this is known as this type of model.
What is a space-filling model?
This is the minimum amount of information needed to know if a compound smells sweet.
What is the shape and functional group?
This is a widely accepted theory of how the interior of the nose detects different smells.
The molecular shape of the molecules has something to do with their...
What is smell?
When a molecule has two double bonds this creates this shape.
What is linear?
The space-filling model is better than a ball-and-stick model because of this flaw.
The sticks do not accurately represent bonds between atoms because a bond is the sharing of electrons and this implies that the atoms are very close to or overlapping each other.
When a molecule is known to be sweet, this is true about its form.
What is stringy?
Molecules ___________ in receptor sites that match their shapes.
What is dock?
This molecule has an asymmetrical shape, with one atom exactly in the center.
What is tetrahedral?
Water is a bent shape because of this.
What are lone pairs?
A space-filling model is unable to show these two things clearly.
1.) the number of bonds between atoms
2.) can hide atoms behind each other.
When something ends in -ate, this is its functional group.
What is ester?
Everything you smell is in the form of molecules is in the ____________ phase.
What is gas?
The space occupied by the electrons; can consist of a bonded pair of electrons, a lone pair of electrons, or multiple bonded pairs of electrons.
What is an electron domain?
Molecules with a triple bond are this shape.
What is linear?
A chain shaped molecule smells like this.
What is sweet?
When a molecule has a nitrogen atom, this is its smell.
What is fishy?
Nerves are ______ when the molecules dock.
What is stimulated?
The tendency for electron pairs to be as far apart from one another as possible; The final shape of a molecule is determined by the fact that electron domains in a molecule are located as far apart from one another as possible.
What is the electron domain theory?
When a molecule contains only 3 electron domains around it and has a double bond, this flat triangle shape is known as this. Formaldehyde is an example of this.
What is trigonal planar?
A camphor smelling molecule is shaped like this.
A minty-smelling molecule is shaped like this.
1.)what is ball-shaped?
2.)What is ring-shaped?
This is the molecular structure of butyric acid
C4H8O2
Mucus is mostly made of this substance.
What is water?
