Question

Which of the following statements are wrong?

• A. Ethyl benezene is the chain isomer of xylene.
• B. Alkenes can exhibit the position chain and geometrical isomerism.
• C. Esters and carboxylic acids are examples of metamerism.
• D. Metamers belong to different classes of compounds.

Answer 1

Answer: (C), (D)

The correct options are
C Esters and carboxylic acids are examples of metamerism.
D Metamers belong to different classes of compounds.

$\begin{array}{c}\text{They are chain isomers because ethyl-bezene has a side}\\ \text{chain of two carbons but xylene has only one carbon in}\\ \text{side chains.}\end{array}$

$\text{Alkenes can exhibit position and}\text{geometric isomerism}$

$\begin{array}{c}\text{Esters and carboxylic acids are examples of functional}\\ \text{isomers as they have different functional groups.}\end{array}$

$\begin{array}{c}\text{Metamers are isomers which differ with respect to}\\ \text{the nature of alkyl groups around a particular functonal}\\ \text{group. Thus, they belong to Same family.}\end{array}$
