hey dear it hunk ur answer is c part hope it helps u
Answer:
(d) butanone is the correct answer.
Explanation:
Diethyl ether is C4H10O.
The linear formula for diethyl ether is C2H5-O-C2H5.
We'll check all options to see the correct answer.
(a) n-propyl methyl ether
It is also called as methoxypropane.
The formula is C4H10O.
It is same as diethyl ether.
Thus it is isomeric with diethyl ether.
(b) butan-1-ol
Butan-1-ol is n butyl alcohol.
It's formula is C4H9OH
The formula is same as diethyl ether.
Thus it is ans isomer of diethyl ether.
(c) 2-methylpropan-2-ol
It is tert butyl alcohol.
It is also called as t-butyl alcohol.
It's formula is (CH3)3COH.
It is same as diethyl ether.
Thus it is an isomer of diethyl ether.
(d) butanone
Butanone is methyl ether ether.
It's formula is C4H8O.
It is different from diethyl ether.
Therefore it is not an isomer of ether.
Hence d) butanone is the correct answer.
Note:
Metamarism is the type of isomerism shown in ethers.
