Question

The total number of head to tail isoprene linkages in the following molecule is .......... 

Hint:

In molecules with isoprene units, count the head-to-tail linkages by identifying how the units are connected in the molecular structure.

Answer 1

Correct Answer: 4

Step 1: Understanding Isoprene Linkages.
Isoprene linkages occur when two isoprene units are connected head-to-tail, forming part of the molecular structure in compounds such as terpenes.

Step 2: Analyzing the Structure.
The given molecule consists of several methyl groups (Me) attached to an alkene chain, representing isoprene units. By counting the head-to-tail linkages of isoprene units in the molecule, we find that there are 5 such linkages.

Step 3: Conclusion.
The total number of head-to-tail isoprene linkages in this molecule is 5, which corresponds to answer (C).
