Identify the functional groups in the following compounds: (a) C₆H₆OH (b) OCH₂CH₂N(C₂H₅)₂ (c) CH=CHNO₂
(a)
Answer
Hydroxyl (-OH)
(b)
Answer
Ether (-O-) and Amine (-N(C2H5)2)
(c)
Answer
Alkene or double bond (-CH=CH-) and Nitro (-NO2)
Explanation
The functional groups are identified based on the specific atoms or bonds present in the given chemical formulas. In (a), the presence of -OH indicates a hydroxyl group. In (b), the oxygen atom between carbons indicates an ether group, and the nitrogen atom indicates an amine group. In (c), the carbon-carbon double bond represents an alkene functional group, and the -NO2 unit represents a nitro group.
