1. C₅H₁₂ 2. C₃H₈O 3. C₃H₆O 4. C₄H₁₀O

Answer: 4. C₄H₁₀O Key idea: metamerism occurs between compounds with the same functional group (usually ethers, ketones, secondary amines) but different alkyl groups on either side of the functional group. mathrmC₄H₁₀O has ethers such as CH₃OCH₂CH₂CH₃ and C₂H₅OC₂H₅ : same group, different alkyl distribution, so metamers. mathrmC₅H₁₂ shows chain isomerism only; C₃H₈O has only one possible ether ( CH₃OC₂H₅ ); C₃H₆O has no pair of ketone metamers.

Answer: 4. \(C_4H_{10}O\)

Key idea: metamerism occurs between compounds with the same functional group (usually ethers, ketones, secondary amines) but different alkyl groups on either side of the functional group.

\(\mathrm{C_4H_{10}O}\) has ethers such as \(\mathrm{CH_3OCH_2CH_2CH_3}\) and \(\mathrm{C_2H_5OC_2H_5}\): same group, different alkyl distribution, so metamers.

\(\mathrm{C_5H_{12}}\) shows chain isomerism only; \(\mathrm{C_3H_8O}\) has only one possible ether (\(\mathrm{CH_3OC_2H_5}\)); \(\mathrm{C_3H_6O}\) has no pair of ketone metamers.
