Nitration occurs through electrophilic addition of aromatic rings by breaking one of its aromatic bonds in order to attack the nitogen. The ring with more electron density will be more likely to add NO2 groups in its meta position (the only position if another group is already attached). When electrophillic addition occurs, the benzene ring would have to unfavorably break its stable aromaticity to attack. However, the phenyl oxygen can donate its electrons to the benzene ring, thus enriching it with electron density and stabilizing the positive charge.
The carbonyl group does nothing to stabilize the other benzene ring during its electrophilic addition. In fact, the carbonyl group may as well have the opposite effect: the resonance structure of a single bonded carbon to its oxygen pulls electrons away from the benzene ring through inductive effect.
Phenyl methanol is actually Benzyl alcohol, C6H5-CH2-OH
The MgBr causes the carbon that it's attached to in the phenylmagnesium bromide to become negative and attack the carbonyl carbon of the ethyl benzoate. The carbonly obtains a new bond with a phenyl group and loses its double bond to oxygen. It instead becomes a single bond and oxygen becomes negative (theoretically, the MgBr will attach to the oxygen as an intermediate phase). This attack of the carbon attached to the MgBr will happen a second time creating a carbon attached to 3 phenyl groups (triphenyl) and upon reduction of this compound (using H2 and a catalyst or LiAlH4), -OCH2CH3 gets protonated and leaves as ethanol, and the carbon and oxygen get protonated to CH3OH. I hope this makes sense to you, lol.
butyric acid
This is a phenyl group linked to an aldehyde.
Phenyl, or Carbolic Acid has a composition of C6H5HO, or C6H6O. that is according to the following website, as of 4th November 2008 http://www.henriettesherbal.com/eclectic/potter-comp/carbolic-acid.html :)
reacting a benzoyl chloride with a phenol to get an phenyl benzoate(ester).

what is the use of phenyl ?
The phenyl is used in the hair care formulations and cosmetics.
First off, if it has Phenyl in it, it is a poison
it has phenyl group to which Mgbr attached at first position
"Phenyl" is only part of a name, you'll need to be more specific.

Nitration of benzoid radicals present in the amino acid side chain occurs due to reaction with nitric acid giving the solutions a yellow colouration. This test is answered by aromatic amino acids like tyrosine and tryptophan. Phenyl alanine gives a weak positive reaction. When a preotein solution is heated with concentrated nitric acid, the benzene ring under goes nitration to form yellow nitro derivatives. When treated with NaOH the sodium salt formed is tense orange in color.
Its common name is B- phenyl butyric acid (B=Beta)
Chemical name of phenyl is 2-phenyl phenol.
