JEE Mains · Chemistry · STD 11 - 9. Hydricarbon
A chloro compound \("A".\) \((i)\) forms aldehydes on ozonolysis followed by the hydrolysis. \((ii)\) when vaporized completely \(1.53\, \mathrm{~g}\) of \(\mathrm{A}\), gives \(448\, \mathrm{~mL}\) of vapour at \(STP.\) The number of carbon atoms in a molecule of compound \(A\) is ...... .
- A \(30\)
- B \(3\)
- C \(0.3\)
- D \(4\)
Answer & Solution
Correct Answer
(B) \(3\)
Step-by-step Solution
Detailed explanation
\(448\, \mathrm{ml}\) of \(\mathrm{A} \Rightarrow 1.53 \,\mathrm{gm} \mathrm{A}\) \(22400\, \mathrm{ml}\) of \(\mathrm{A} \Rightarrow \frac{1.53}{445} \times 22400\, \mathrm{gm} \,\mathrm{A}=7650\)…
