What is the relationship between compounds I and II They are

What is the relationship between compounds I and II? They are: enantioners identical different conformation of the same compound constitutional isomers Select the structure of benzyl methyl ether. Which compound would have the highest boiling point?

Solution

(1).D The twisting about carbon-carbon bond results in the formation of different conformations of cyclohexane.Chair conformation is the most stable conformation of cyclohexane.4 chair conformations are possible for 1,3-disubstituted cyclohexanes.(a,a),(e,e),(e,a),(a,e).

Compounds I and II are different conformations of the same compound.

(2) II Ethers can be named by naming each of the two carbon groups as a separate word followed by space and the word ether as in the question,the two carbon groups are benzyl and methyl.

(3) III Alcohols exhibit considerable dipole moment due to the presence of electronegative oxygen.The alcohol molecules form intermolecular hydrogen bond easily,which makes the boiling point of alcohols higher . The ether and ketone molecules are not associated through hydrogen bonding due to which their boiling points are much lower than isomeric alcohols.
