Question

how to count the number of isoprenes in a molecule and also how to know wether a molucle is aromatic or not

Answer 1

Formally, 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.

2)

Aromatic molecules have the following characteristics:

1. They are cyclic.
2. They are conjugated all around the ring. The easiest way to put it is this: every atom in the ring must be able to participate in resonance. ...
3. the molecule must have (4n+2) Pi electrons. ...
4. The molecule must be fla
