Because in homo-annular ring distance between C1 and C4(of butadiene structure in it) is less compare to C1 and C4 of heteroannular.
So, in Homo-annular more overlap of pi system, more conjugation, more lamda max.
The hydrocarbons involved in Diels -alder reactions are any 1'3 diene and a dienophile (hydrocarbon having one double or triple bond)
Havoc Clone? definitely not a havoc clone. havoc is methylated and is epistane. this is a progestin, similar to 13-ethyl (max-lmg) with a few structural differences. also, these are two separate compounds. 12-ethyl-3-methoxy-gona-diene is a prohormone while the rest is an aromatase inhibitor.
Chemical Spider mention the name 2λ4-Diazathia-1,2-diene-1,3-diyldisulfanide.
there is cyclobut-1-ene but-2-yne but-1-yne 3-methylcycloprop-1-ene but-1,2-diene but-1,3-diene 2-methylcycloprop-1-ene and two more nameless ones, which have the line diagrams: /|\ \|/ and /_\
Those aren't equal signs, those are double bonds. When there are two double bonds in a compound, it has the suffix: -diene. So, we have 4 carbons, which means it's a but-, and 6 Hydrogens. So the formula is C4H6: 1,3-butadiene

Possibly because it is a 1,3-diene. A more interesting question would be why does it sometimes not behave that way.
There isn't a direct correlation. Bromine Number is a measure of the amount of olefins in a sample. Diene Valve is a measure of the conjugated diolefins in a sample. In hydrocarbons, samples with high Diene Value also tend to have high Brominie numbers as a result of processing in a hydorgen deficient atmosphere.

Ethylene-Propylene-Diene-Monomer.
The monomer of neoprene is 2-chlorobuta-1,3-diene (C4H5Cl).
No he didn't diene is still alive doing freaky things.
I. J. Gardner has written: 'Conjugated Diene Butyl'

Yes, They have a conjugated double bonds that will react with a dienophile
An alkadiene is an aliphatic diene, an organic compound with double bonds in which the carbon atoms are arranged in an open chain.
Here are three ways: "Diene Schwestern", "Ihr Schwestern", and "Ihre Schwestern".
