Question

How may carbon atoms are there in the simplest bicyclo compound?

• A. 4
• B. 5
• C. 6
• D. None of these

Answer 1

The correct option is A

4

For a bicycle compound, we need;

$\to$ Two fused cycloalkane rings with 2 or more common carbon atoms.

The simplest cycloalkane has 3 carbon atoms. When we fuse two cyclopropane rings together. So that they have exactly two common carbon atoms

we get .

This would be the simplest bicyclo compound. It has 4 carbon atoms.

So, the answer is A
