Q. 63

Note : In the following questions a statement of assertion followed by a statement of reason is given. Choose the correct answer out of the following choices.

Assertion : IUPAC name of the compound is 2-Ethoxy-2-methylethane.

Reason : In IUPAC nomenclature, ether is regarded as hydrocarbon derivative in which a hydrogen atom is replaced by —OR or —OAr group [where R = alkyl group and Ar = aryl group]

A. Assertion and reason both are correct and reason is correct explanation of assertion.

B. Assertion and reason both are wrong statements.

C. Assertion is correct statement but reason is wrong statement.

D. Assertion is wrong statement but reason is correct statement.

E. Both assertion and reason are correct statements but reason is not correct explanation of assertion.

Answer :


We number the primary chain. We observe a 3 carbon ether group is joined with the second carbon of main chain.


Since ethers have naming conventions like alkoxyalkane where alkoxy represents the carbon number present in the ether part and alkane represents the carbon number joined with it.


So according to it, we get the IUPAC name to be 2-propoxypropane.


And yes, indeed in IUPAC nomenclature, ether is a hydrocarbon derivative where an hydrogen atom is replaced by –OR or –OAr group. As mentioned earlier, these are alkoxy groups as alkane and oxygen both are present simultaneously.
