Yes, there are lots of substances wich have four C=C double bonds. E.g. there is cycloocta-1,3,5,7-tetraen (C8H8) which is a ring of 8 carbon atoms and 4 double bonds distributed equally in the ring. If you consider the bonds in benzene containing 3 double bonds (some might disagree) then vinyl benzene is another compound with four double bonds. The IUPAC nomenclature meaning "4 double bonds" is "tetraen" (although not every compound with four double bonds necessarily has the fragment "tetraen" in its name. In case the question was "is there a substance where /one carbon atom/ has four different double bonds?" the answer is: No, at least I haven't seen one, and if there were, it would probably have extremely short lifespan and decompose to something less crowded.
CH4
There are four bonds.All are covalent bonds.
The substance not paired correctly isCl2 - polar covalent bonds.
Maximum of four bonds. It can form four
Diamond is a covalent substance in which every carbon atom is linked with four other carbon atoms tetrahedraly through covalent (sigma) bonds.
it has four covalent bonds and four hydrogen atoms in it you dumbo

MOLECULE
it is a molecule
Covalent bonds are the easiest to break, since they are the easiest to make. But no substance is made when bonds break.
