Step-by-step explanation:
Alcohol is an organic compound which carbon and hydrogen atoms. One of the carbon atom of an alcohol is attached to "-OH" group. This means that the functional group present in an alcohol is "-OH" group.
General chemical formula of an alcohol is ROH.
Ether is also an organic compound and along with carbon and hydrogen atoms an oxygen atom is present in the compound. This means than ether contains the functional group "-O". General chemical formula of ether is ROR'; where Rand R' can be same or different alkyl/aryl groups.
A carbonly group contains a carbon atom attached to a doubly bonded oxygen atom. General formula of a carbonyl compound is RCOR'.
A polymer is defined as a substance that consists of repeated monomer units.
Therefore, the given terms are matched appropriately as follows.
- Alcohol - B) Contains an oxygen and hydrogen (−O−H) bonded to a carbon
- Ether - D) Contains an oxygen bonded within the carbon chain
- Carbonyl group - C) Contains a carbon atom double-bonded to an oxygen atom
- Polymer - A) Extremely long molecule chain with repeated molecular units
