Observe the following sequence of reaction and answer the questions based on it. Phenylacetylene overset(CH_(3)MgBr)underset(-CH_(4))to x overset((i)CO_(2))underset((ii)H^(o+))to y overset(H_(2)O //H_(2)SO_(4))underset(HgSO_(4))to z overset(Delta)to w Which of the following statement is not correct

Answer»

y decolourises `Br_(2)//H_(2)O` solution
z on heating liberates `CO_(2)` gas
w on reaction with NAOL GIVES yellow ppt
x liberates `H_(2)` gas with Na metal
