Any substance containing that peculiar carbon chain with two double links C=C-C=C can double up—polymerize, the chemist calls it—into a rubber-like substance.
If the carbon chain contains one or more double linkages we get the "flowery" perfumes.
The number represents the position of the first of the two carbons making the bond, in the longest carbon chain.
It is blocked from nucleophilic attack on one side of the carbon chain by the first bromine atom and can only attack from the other side.
Kroto realized that by using a graphite target, any carbon chains formed could be studied.
Faecal recoveries of alkanes in equids do not appear to show the same influence of carbon chain length that has been observed in ruminant studies.
In these cases, alkane carbon chain length had a small effect on relative recovery.
Faecal recoveries of alkanes in equids do not show the same influence of carbon chain length that is evident for ruminants.
