In the following carbylamine reaction,$x$ represents the moles of $KOH$ consumed:
$C_6H_5NH_2 + CHCl_3 + x KOH \rightarrow C_6H_5NC + 3KCl + 3H_2O$
Find the value of $x$.

What is the correct order of basic strength in substituted amines in an aqueous solution?

Given below are two statements :
Statement $I$: Aniline reacts with conc. $H_2SO_4$ followed by heating at $453-473 \ K$ to give $p$-aminobenzene sulphonic acid (sulphanilic acid). This compound contains both nitrogen and sulphur,and thus it gives a blood red colour in the 'Lassaigne's test' due to the formation of ferric thiocyanate,$[Fe(SCN)]^{2+}$.
Statement $II$: In Friedel-Craft's alkylation and acylation reactions,aniline forms a salt with the $AlCl_3$ catalyst. Due to this,the nitrogen atom of aniline acquires a positive charge and acts as a deactivating group,preventing further reaction.
In the light of the above statements,choose the correct answer from the options given below :

Explain the acylation of ethanamine and aniline.
