KCET2012ChemistryGeneral Organic Chemistry
An oxygen containing organic compound was found to contain 52 % carbon and 13 % of hydrogen. Its vapour density is 23 . The compound reacts with sodium metal to liberate hydrogen. A functional isomer of this compound is
Options
- Aethanal
- Bmethoxy methane
- Cmethoxy ethane
- Dethanol
Correct answer
B. methoxy methane
Step-by-step solution
Empirical formula of the compound = C ₂ H ₆ O and empirical formula weight =2 12+6 1+16=46 Molecular weight =2 vapour density Molecular weight =2 23=46 n = 46 46 =1 Molecular formula of the compound = C ₂ H ₆ O Compound liberates H ₂ with Na . It must be alcohol, C ₂ H ₅ OH (ethanol) Its functional isomer is CH ₃ OCH ₃ (methoxy methane)
