Question

Write down the structural isomeric ethers corresponding to the molecular forluma `C_5H_(12)O`.
`DBE=(sumn(v-2))/(2)+1`
`=(5(4-2)+12(1-2)+1(2-2))/(2)+1=0`
This implies that only saturated acyclic ethers are to be considered

Answer 1

Six isomeric ethers are possible:
`underset(1-"methoxybutane")(CH_(3)-O-overset(1)(C)H_(2)-CH_(2)-CH_(3))`
`underset(1-"Ethoxypropane")(CH_(3)CH_(2)O-overset(1)(C)H_(2)CH_(2)CH_(3))" "underset(2-"Methoxybutane")(CH_(3)Ooverset(.^(1)CH_(3))overset(|)(.^(2)CH_(2))overset(3)(C)H_(2)-overset(4)(C)H_(3))` ltrgt `underset(2-" Ethoxypropane")(CH_(3)CH_(2)O-underset(CH_(3))underset(|)overset(2)(C)H_(2)CH_(3))" "underset(1-"Methoxy-2-methylpropane")(CH_(3)O-overset(1)(C)H_(2)underset(CH_(3))underset(|)overset(2)(C)HCH_(3))`
`underset(2-"Methoxy-2-methylpropane")(CH_(3)O-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-CH_(3))`
