(a)
Interpretation: The Lewis structures for each of the molecules present in
Concept Introduction:Isomers: Are the compounds that have same molecular formula but different arrangement of atoms and properties.
(a)
Answer to Problem 9STP
Explanation of Solution
The two isomers present in
Isomers | Formula | Lewis structure | |
1. |
Ethanol | ||
2. |
Dimethyl ether |
(b)
Interpretation: The
Concept Introduction : Functional group: An atom or group ofatoms in a hydrocarbonderivative that containselements in addition tocarbon and hydrogen.
(b)
Answer to Problem 9STP
Explanation of Solution
Since, ethanol is an alcohol as the functional group is −OH
And dimethyl ether is an ether group as the functional group is −O−
(c)
Interpretation: The molecules that would exhibit the stronger intermolecular forces needs to be determined.
Concept Introduction : Hydrogen bonding: Special name forunusually strong dipole−dipole attractions thatoccur among moleculesin which hydrogen isbonded to a highlyelectronegative atom(such as nitrogen,oxygen, or fluorine)
(c)
Answer to Problem 9STP
Ethanol will exhibit stronger intermolecular force than dimethyl ether.
Explanation of Solution
Since, ethanol has a hydrogen bond that is O-H bond and it is a colorless liquid that boils at
