Mechanism, color writing with

Carotene is a highly conjugated hydrocarbon with an orange-red color. Its biosynthesis occurs via the isoprene pathway (Special Topic E in WileyPLUS), and it is found in, among other sources, pumpkins. One of the chemical syntheses of /3-carotene was accomplished near the turn of the twentieth century by W. Ipatiew Ber. 1901, 34, 594-596). The first few steps of this synthesis involve chemistry that should be familiar to you. Write mechanisms for all of the reactions from compounds 2 to 5, and from 8 to 9 and 10. 

Write a mechanism for the reactive dyeing of cellulose (designate it as ROH) with 24.30 (X is the chromophore, the part of the molecule that gives rise to the color) ...
