Question

Which of the following is ether?

• A. R–C=O
• B. R–C=O
• C. R–O–R
• D. HO–C=O

Hint:

Ethers are often referred to as “alkoxy alkanes” and are used as solvents due to their low reactivity.

Answer 1

The Correct Option is C

Step 1: Understanding ether.
An ether is an organic compound in which an oxygen atom is bonded to two alkyl or aryl groups (R–O–R’).
Step 2: Analysis of options.
(A) R–C=O: Represents carbonyl group (aldehydes or ketones), not ether.
(B) R–C=O: Same as above, carbonyl compound.
(C) R–O–R: Correct, this is the general structure of ethers.
(D) HO–C=O: Represents carboxylic acid group, not ether.
Step 3: Conclusion.
The correct answer is (C) R–O–R.
