Question

Write the condensed structures of all isomers with the formula C₂H6H₂. Label the functional group (or groups) of each isomer.

a) CH₃OCH₂OH (Methoxymethanol) - Ether
b) CH₃OCH₃ (Dimethyl ether) - Ether
c) CH₃COOH (Methanoic acid) - Carboxylic acid
d) CH₃CH₂OCH₃ (Ethyl methyl ether) - Ether

Answer 1

The provided chemical formula C₂H₆H₂ seems to be a typo. The correct isomers should be for formulas C₂H₆O or C₂H₆O₂. For C₂H₆O, the isomers are CH₃OCH₃ (dimethyl ether) and CH₃CH₂OH (ethanol), while for C₂H₆O₂, the isomers are a) CH₃OCH₂OH (methoxymethanol) and c) CH₃COOH (acetic acid).

Step-by-step explanation:

The student has made a typo in the chemical formula provided. The correct formula for the isomers should be either C₂H₆O or C₂H₆O₂, not C₂H₆H₂. For isomers of C₂H₆O, there are two possibilities: an ether and an alcohol. The condensed structures and functional groups of the isomers of C₂H₆O are:

• Dimethyl ether (Ether): CH₃OCH₃
• Ethanol (Alcohol): CH₃CH₂OH

For isomers of C₂H₆O₂, there are also two possibilities: a carboxylic acid and a different type of ether. The condensed structures and functional groups of isomers of C₂H₆O₂ are:

• Methoxymethanol (Ether): CH₃OCH₂OH
• Acetic acid (Carboxylic acid): CH₃COOH
