The ammonia evolved from $2 \mathrm{g}$ of a compound in Kjeldahl's estimation of nitrogen neutralizes $10 \mathrm{mL}$ of $2 \mathrm{M}$ ${\mathrm{H}}_2{\mathrm{SO}}_4$ solution. The weight percentage of nitrogen in the compound is:

Among $\mathrm{HCl}, \mathrm{HBr}, \mathrm{HF}$, and $\mathrm{HI}$, the weakest acid in water is:

Write the basicity order of the following:

Consider the following three halides:
($\mathrm{i}$) ${\mathrm{CH}}_3-{\mathrm{CH}}_2-\mathrm{Cl}$
($\mathrm{ii}$) ${\mathrm{CH}}_2=\mathrm{CH}-\mathrm{Cl}$
($\mathrm{iii}$)${\mathrm{C}}_6{\mathrm{H}}_5-\mathrm{Cl}$
Arrange the $\mathrm{C}-\mathrm{Cl}$ bond length of these compounds in the decreasing order.

The order of acidity of compounds $\mathrm{I}-\mathrm{IV}$ is
