The structure of bicyclo [1, 1, 0] butane is :

Comprehension In addition to the standar ring systems (such as cyclohexane), cyclic compounds can also be bicylic tricylic, etc. or they can be spirocyclic, bicyclic or bridge head carbons. The point of attachment of two rings are called bridge head atoms. The formal names of bicyclic and related ring system are based on (a) Total number of atoms in the molecule. (b) The number of atoms in each bridge connecting the bridge head atoms. These number are written square bracket in decreasing order. Spirocyclic compounds have two fused rings, but only one bridge head atom. Spirocyclic compounds and named like bicyclic compounds, but have the prefix spirocyclo. Answer the following question : Which of the following is the correct structure of bicyclo [1.1.0] butane?
