The correct IUPAC name of is

Options

  1. ATertiary butoxy ethane
  2. B1,1-Dimethyl-1-ethoxyethane
  3. C2-ethoxy-2-methyl propane
  4. DEthoxy tertiary butane

Correct answer

C. 2-ethoxy-2-methyl propane

Step-by-step solution

To find the correct IUPAC name for the given ether, we follow these steps: 1. Identify the longest continuous carbon chain to serve as the parent alkane. The alkyl groups attached to the oxygen atom are an ethyl group ( -C₂H₅ ) and a tert-butyl group ( -C(CH₃)₃ ). 2. The longest carbon chain in the tert-butyl group has 3 carbon atoms. Therefore, the parent alkane is propane. 3. Number the parent chain to give the substituents the lowest possible locants. Numbering from either end of the 3-carbon chain gives the cen
