- 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.arrow_forwardDon't USE AIarrow_forwardDon't USE AIarrow_forward
