UV Visible Spectroscopy

Spectroscopy refers to the absorption or emission of light or other radiations by matter. When a substance or chemical absorbs light or radiation, they reach an excited state followed by de-excitation or emission of the light or radiation forming distinct spectra. UV-visible spectroscopy or ultraviolet-visible refers to the absorption and emission in the ultraviolet and visible regions of the electromagnetic spectrum.

The instructions were to define if the molecule was aromatic or antiaromatic. If the element (such as N or O) has a double bond directly on it, then its lone pair doesn't count in the conjugation system; if there's a single bond, then its lone pair is counted. I counted the electrons on the lone pairs, and since the total was 6 e-, I labeled it as aromatic. was this correct?
How many pi electrons are there in the two aromatic rings of biphenyl?
Compound A whose molecular formula is C9H11ClO, is found to be aromatic, and on vigorous oxidation with hot, concentrated, basic potassium permanganate followed by acidification, a new aromatic, compound B with the molecular formula of C7H5ClO2 is formed. On treatment with bromine and a ferric bromide catalyst, compound B produces ONLY 2 monobrominated derivatives, compounds C and D, each having the molecular formula C7H4BrClO2. On treatment with sodium metal, compound A produces bubbles of hydrogen gas. Controlled oxidation of compound A with PCC first gives compound E, with formula C9H9ClO. Compound E produces a silver mirror with Tollen’s reagent. Mild oxidation of compound E by chromic acid produces compound F, with the molecular formula C9H9ClO2 which turns blue litmus red. When compound A is heated with concentrated sulfuric acid, a single compound G, whose molecular formula is C9H9Cl, is produced. On ozonolysis followed by reaction with dimethyl sulfide, compound G gives…
