What  carbon-carbon bond forming reaction would you want to consider to synthesize the following compound?

Give detailed solution of the question and i request you please give the explanation of correct and incorrect option

The dehydration of compound A produces many different products. One of the products formed is compound G. Can you figure out the mechanism? The mechanism proceeds through five intermediates (compounds B-F). Sort the intermediates according to the reaction mechanism which includes a methyl shift, a hydride shift and a resonance structure. Note: treat resonance structures as individual steps. Compound III Compound IV Compound II Compound I Compound V Your answer compound A OH compound G intermediates II

You have a carbonyl compond, you then have to replace the oxygen atom from it and replace it with another atom. show step by step process and explain each step in detail.

Draw both resonance structures of the anion formed by the reaction of the most acidic C-H bond of the compounds below with base.
