Final answer:
The condensed structures of the isomers C2H6O are as follows: a) CH3CH2OH (Ethanol) - Alcohol; b) CH3OCH3 (Dimethyl ether) - Ether; c) CH3CHOHCH3 (Isopropanol) - Alcohol; d) CH3CH2CH2OH (1-Propanol) - Alcohol.
Step-by-step explanation:
a) CH3CH2OH (Ethanol) - Alcohol: In this isomer, the functional group is the hydroxyl group (-OH) which is attached to the carbon chain.
b) CH3OCH3 (Dimethyl ether) - Ether: In this isomer, the functional group is the ether group (-O-) which connects two carbon chains.
c) CH3CHOHCH3 (Isopropanol) - Alcohol: In this isomer, the functional group is again the hydroxyl group (-OH) which is attached to a carbon chain that is connected to two other carbon chains.
d) CH3CH2CH2OH (1-Propanol) - Alcohol: In this isomer, the functional group is once again the hydroxyl group (-OH) which is attached to the end of a carbon chain.
