Which of the following is general formula of ether?

Correct answer: A. R-O-R'

  • A. R-O-R'
  • B. (Cn + H2n+1) CO
  • C. CnH2n+1CHO
  • D. (Cn H2n+1 COOCn H2n+1)

Explanation

The correct answer is Option A: R-O-R'. Ethers are characterized by an oxygen atom bonded to two alkyl or aryl groups, symbolized by R and R'. Option B, (Cn + H2n+1) CO, is not related to ethers and does not represent any typical organic structure. Option C, CnH2n+1CHO, represents aldehydes, which have a carbonyl group. Option D, (Cn H2n+1 COOCn H2n+1), represents esters, which contain a carbonyl group adjacent to an ether linkage.
