The compound shown is a bridged bicyclic hydrocarbon. Write its von Baeyer name as bicyclo[x.y.z]alkane with x >= y >= z, and give the value of x + y + z as an integer.
Numerical answer type, tolerance 0.5.
Answer: 8
The compound is bicyclo[3.3.2]decane. The two bridgeheads are joined by bridges of 3, 3 and 2 carbons (10 carbons in all, 8 of them in the bridges). So x + y + z = 3 + 3 + 2 = 8.
