Question

what is isoprene rule?​

Answer 1

Answer:

Explanation:

Isoprene rule stats that the terpenoid molecules are constructed from two or more isoprene unit. ... Special isoprene rule states that the terpenoid molecule are constructed of two or more isoprene units joined in a 'head to tail' fashion.

Answer 2

Isoprene rule:

• According to the isoprene rule, there are no 1-1 or 4-4 linkages in most naturally occurring terpenes.

• Two or more isoprene molecules are connected in the production of terpenes.
• Given that the head and tail of the molecule are predominantly engaged in the linking, there are three possibilities for linking between two isoprene molecules:

• 1-1 Linkage:

• One isoprene molecule's head could connect to the head of another isoprene molecule.
• 1–4 Linkage:
• One isoprene molecule's head could connect to the tail of another isoprene molecule.
• 4-4 Linkage:
• One isoprene molecule's tail could connect to the tail of another isoprene molecule.
