All but one of the following compounds react with aniline to give acetanilide. Which one does not?

What are $X$ and $Y$ respectively in the following set of reactions?

In the given reaction,identify the final product.

An organic compound $A$ contains nitrogen and chlorine. It dissolves readily in water to give a solution that turns litmus red. Titration of compound $A$ with standard base indicates that the molecular weight of $A$ is $131 \pm 2$. When a sample of $A$ is treated with aqueous $NaOH$,a liquid separates which contains $N$ but not $Cl$. Treatment of the obtained liquid with nitrous acid followed by phenol gives an orange precipitate. The compound $A$ is:

Major end product of the following sequence of reaction is: $CH_3-CH_2-CH_2-CONH_2$ $\xrightarrow{Ca(OH)_2, Cl_2, \Delta} X$ $\xrightarrow{HNO_2} Z$

From $6.55 \ g$ of aniline,the maximum amount of acetanilide that can be prepared will be _ $\times 10^{-1} \ g$.
