Which reactant will give the following alcohol on reaction with one mole of phenyl magnesium bromide $(PhMgBr)$ followed by acidic hydrolysis?

The mass of $NH_3$ produced when $131.8 \ kg$ of cyclohexanecarbaldehyde undergoes Tollen's test is $..... \ kg$. (Nearest Integer) Molar Mass of $C = 12 \ g/mol$,$N = 14 \ g/mol$,$O = 16 \ g/mol$.

Benzene carbaldehyde (benzaldehyde) is reacted with concentrated $NaOH$ solution to give the products $A$ and $B$. The product $A$ can be used as a food preservative and the product $B$ is an aromatic hydroxy compound where the $OH$ group is linked to an $sp^3$ hybridized carbon atom next to the benzene ring. The products $A$ and $B$ are respectively,
