Some Basic Concepts of Chemistry - Result Question 37

####37. An organic compound containing $C, H$ and $N$ gave the following analysis :

$C = 40$

Its empirical formula would be

[1998]

(a) $C_{2} H_{7} N_{2}$

(b) $C H_{5} N$

(d) $C_{2} H_{7} N$

Show Answer

Solution:

Table for empirical formula

$Unknown environment 'tabular'$ & $Unknown environment 'tabular'$ & Ratio \ \hline $C$ & 40.00 & 12 & $\frac{40}{12} = 3.33$ & $\frac{3.33}{3.33} = 1$ \ \hline $H$ & 13.33 & 1 & $\frac{13.33}{1} = 13.33$ & $\frac{13.33}{3.33} = 4$ \ \hline $N$ & 46.67 & 14 & $\frac{46.67}{14} = 3.33$ & $\frac{3.33}{3.33} = 1$ \ \hline \end{tabular}

Hence, empirical formula $= C H_{4} N$
