Hint: Sometimes there is more than one way to connect a given group of atoms into a molecular structure. They have the same formula but different structures which gives them their unique properties.
Complete step by step solution:
A. This is called isomerism. Isomers are the molecules which have the same molecular formula, but have a different arrangement of the atoms. They have the same empirical formula but they do not necessarily share similar physical and chemical properties.
B. The structural formula of A (\[C{{H}_{3}}C{{H}_{2}}OH\]) is
The structural formula of B (\[C{{H}_{3}}OC{{H}_{3}}\]) is
C. Common name: Ethyl alcohol
IUPAC name: Ethanol
Common name: Dimethyl ether
IUPAC name: Methoxymethane
D. The functional group of A is alcohol.
The functional group of B is ether.
Additional Information:
At room temperature, dimethyl ether is a gas whereas ethanol is a liquid.
The dominant intermolecular attraction between ethanol molecules is hydrogen bonding whereas in dimethyl ether the major intermolecular attraction involves regular dipole moments.
Dimethyl ether has a melting point of -138°C and boiling -25°C while ethanol has a melting point of -117°C and boiling 78°C.
Note: These two compounds are functional isomers. There are even more types of isomers, mainly classified as chain isomers, position isomers, and functional group isomers.
