Question

Which of the following is a metamer of $C{H}_{3}C{H}_2-S-C{H}_{2}C{H}_3$?

• A. $C{H}_3-S-C{H}_{2}C{H}_{2}C{H}_3$
• B. $C{H}_{3}C{H}_2-O-C{H}_{2}C{H}_3$
• C. $C{H}_3-O-C{H}_{2}C{H}_{2}C{H}_3$
• D. None of these

Answer 1

The correct option is A

$C{H}_3-S-C{H}_{2}C{H}_{2}C{H}_3$

Compounds having the same molecular formlua but different number of carbon atoms(or alkyl group) on either side of the functional group are called metamers and this phenomenon is called metamerism.Metamerism occurs among the members of the same homologus family.

Therefore necessary conditions are:

$\to$ Same molecular formula

$\to$ Same functional group

$\to$ Different number of carbon group on either side of the functional group.

Therefore ,correct answer is:

$C{H}_3-S-C{H}_{2}C{H}_{2}C{H}_3$
