I have an organic

chemistry question, I need help with all parts (photos attached). Thanks a ton multiplicity is tough to grasp.

3.(20 marks) When 2,2-dimethyl-4-bromopentane is treated with silver(I) in the presence of water,the reaction can give a variety of products: direct substitution or formation of an alcohol viacarbocation rearrangement(s), or elimination to form an alkene:AlcoholsAg*, H20(substitution)-BrIntermediateRearrangement(s)Alkeneselimination)The following 1H and 13C NMR spectra were taken of one product A obtained from this reaction.Complete spectra are provided: 1H NMR from 0.5 to 5.0 ppm and 13C NMR from 0 to 160 ppm.
