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 \(\underline{C}\),
- B \(\mathrm{HO}-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{CO}_2 \mathrm{H}\)
- C \(\mathrm{HO}-\mathrm{CH}_2-\mathrm{CO}_2 \mathrm{H}\)
- D \(\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{CO}_2 \mathrm{H}\)
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…
