Question

Draw all constitutionally isomeric ethers with the molecular formula C₄H₁₀O. Provide a common name and a systematic name for each isomer

Answer 1

To draw all constitutionally isomeric ethers with the molecular formula C₄H₁₀O, we need to consider the different ways the atoms can be arranged. The three constitutionally isomeric ethers with the molecular formula C₄H₁₀O are 1-ethyl-2-methoxyethane, 1-propyl-2-methoxypropane, and 1,1-dimethoxybutane.

Step-by-step explanation:

Constitutionally Isomeric Ethers

Ethers have the general formula R-O-R', where R and R' can be any alkyl or aryl groups. To draw all constitutionally isomeric ethers with the molecular formula C₄H₁₀O, we need to consider the different ways the atoms can be arranged.

1. 1. Add an ethyl group (C₂H₅) to one carbon and a methyl group (CH₃) to the other carbon. This is 1-ethyl-2-methoxyethane.
2. 2. Add a propyl group (C₃H₇) to one carbon and a methyl group (CH₃) to the other carbon. This is 1-propyl-2-methoxypropane.
3. 3. Add two methyl groups (CH₃) to one carbon and two methyl groups (CH₃) to the other carbon. This is 1,1-dimethoxybutane.

These are the three constitutionally isomeric ethers with the molecular formula C₄H₁₀O.
