$${\text{2CH}} \equiv {\text{CH}}\xrightarrow[{{\text{N}}{{\text{H}}_{\text{4}}}{\text{Cl}}}]{{{\text{CuCl}}}}{\text{A}}\,\xrightarrow[{{\text{Pt/BaS}}{{\text{O}}_{\text{4}}}}]{{{{\text{H}}_{\text{2}}}}}{\text{B}}\xrightarrow{{{\text{B}}{{\text{r}}_{\text{2}}}}}{\text{C}} $$  

 Major product "P" obtained in the given reaction is:

$$Al_4C_3 \xrightarrow{Hydrolysis } A \xrightarrow[HNO_3(vapour)]{400^o-479^oc}B$$;

What is the major product in the given reaction:

During halogenation of methane, methylene dichloride reacts with chlorine to form:

$$ { CH }_{ 3 }-{ CH }_{ 2 }-OH\xrightarrow [  ]{ PCC } A\xrightarrow [ OH^{ - } ]{  } B $$
Then 'B' is
