What is IUPAC name of the following compound?
Options
- A1-Methoxy-3,3-dimethylcyclobutane
- B3-Methoxy-1,1-dimethylcyclobutane
- C3,3-dimethylcyclobutoxymethane
- D1-methoxy-3-isopropyl butane
Correct answer
B. 3-Methoxy-1,1-dimethylcyclobutane
Step-by-step solution
To determine the IUPAC name of the ether compound with a cyclobutane ring, substituents are identified as a methoxy group and a geminal dimethyl group. The parent structure is cyclobutane. Numbering begins at the carbon bearing the dimethyl group to achieve the lowest set of locants (1,1,3) rather than (1,3,3). This yields the systematic name 3-methoxy-1,1-dimethylcyclobutane , corresponding to option B. Among the given choices, only option B uses the correct numbering and substituent identification.
