(a)

Interpretation Introduction

Interpretation:

Whether the given error is systematic or random has to be stated.

Concept Introduction:

Systematic error:

These error occur due to instrumental flaws or due to errors in experimental design. These errors can be replicated. It can be detected and corrected. These errors are otherwise called as determinate errors.

Random error:

Random errors are uncontrollable, unpredictable and are completely random. These errors are not reproducible. These are caused due to instrumental changes or due to the change in the measuring environment. Random errors has an equal chance of being positive and negative. These errors are otherwise called as indeterminate errors.

To state: Whether the given error is systematic or random

Draw and show the full mechanism of how the molecule ((1E, 3E, 5E)-1-methoxyhepta-1,3,5-triene) is built using substitution and elimination reactions. You can start with an alkane of any carbon length with any number of leaving groups attached or with a alkoxide of any carbon length (conjugate base of an alcohol). Show each step and and explanation for each reaction. Also include why the reagents and solvents were picked and what other products can be expected.
