One per cent composition of an organic compound \(A\) is, carbon : \(85.71 \%\) and hydrogen \(14.29 \%\). Its vapour density is 14 . Consider the following reaction sequence
Identify \(\underline{C}\),

  1. B \(\mathrm{HO}-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{CO}_2 \mathrm{H}\)
  2. C \(\mathrm{HO}-\mathrm{CH}_2-\mathrm{CO}_2 \mathrm{H}\)
  3. D \(\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{CO}_2 \mathrm{H}\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(\mathrm{HO}-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{CO}_2 \mathrm{H}\)

Step-by-step Solution

Detailed explanation

\(\begin{aligned}& \mathrm{C}=85.71 \% \quad=\frac{85.71}{12}=7.14 ; \quad \frac{7.14}{7.14}=1 \\& \mathrm{H}=14.29 \% \quad=\frac{14.29}{1}=14.29 ; \quad \frac{14.29}{7.14}=2\end{aligned}\) \(\therefore \quad\) Empirical formula \(=\mathrm{CH}_2\)and, empirical formula weight…
