Question

If a compound contains two oxygen atoms, four carbon atoms and number of hydrogen atoms is double of carbon atoms, the vapour density of it is

• A. 88
• B. 44
• C. 132
• D. 72

Answer 1

The correct option is B 44

If a compound contains two oxygen atoms, four carbon atoms and number of hydrogen atoms is double of carbon atoms, the molecular weight=$2\times 16+4\times 12+8\times 1$=88. The vapour density of it $=\frac{88}{2}=44$
