Some Basic Principles Of Organic Chemistry Question 146

Question: A hydrocarbon contains 10.5 gm carbon and 1gm hydrogen. Its 2.4 gm has 1 litre volume at 1 atm and $127^{o} C$ , hydrocarbon is [UPSEAT 2003]

Options:

A) $C_{6} H_{7}$

B) $C_{6} H_{8}$

C) $C_{5} H_{6}$

D) None of these

Show Answer

Answer:

Correct Answer: A

Solution:

$C = 10.5 g m = \frac{10.5}{12} m o l = 0.87 m o l$

$H = 1 g m = \frac{1}{1} = 1 m o l$
$∴, {(C_{0.87} H_{1})}_{7} = C_{6.09} H_{7} \approx C_{6} H_{7}$

$P V = n R T$ ; $P V = \frac{w}{m} R T$

$1 \times 1 = \frac{2.4}{m} \times 0.082 \times 400$

$m = 2.4 \times 0.082 \times 400$

$= 78.42 \approx 79$ .
