Bicycloundecane is an organic compound with molecular formula C11H20.
It is essentially the spherical form of the ring cycloundecane.
In cycloundecane, the eleven carbon atoms are joined together in a chain that meets at the ends to form a ring.
Each non-bridgehead carbon atom is attached to two hydrogen atoms making bicycloundecane a saturated compound.
It is one of several bridged hydrocarbon residues that are formed during the thermohardening of polymerizable conductive adhesives based on di(metha)acroyloxymethyl-tricyclodecane, organic peroxide, and thermoplastic resin; such adhesives have applications in electronics.
