Answer: 
Hi, The special isoprene rule describe the ''haid to tail'' linkage-structure of isoprene units in terpenoid molecules. According to this fashion, branched portion of isoprene unit acts as the head whereas the unbranched one is the tail.

Answer: 
In biosynthesis of terpenes, two or more isoprene molecules are linked to one another. Linking between two isoprene molecules could occur in three ways, given that the head and the tail of the molecule are primarily involved in the linking 1.The head of one isoprene molecule could link with the head of another isoprene molecule. 2.The head of one isoprene molecule could link with the tail of another isoprene molecule. 3.The tail of one isoprene molecule could link with the tail of another isoprene molecule. http://science.uvu.edu/ochem/index.php/alphabetical/i-j/isoprene-rule/
