C6H5C≡NC6H5C≡N and C6H5 N→=CC6H5 N=→C exhibit whichtype of isomerism?BITSAT 2011

Breakdown the Problem

1. Identify the given compounds and their structures.
2. Determine the types of isomerism present between the compounds.

Relevant Concepts

• Isomerism refers to the phenomenon where two or more compounds have the same molecular formula but different structures or arrangements of atoms.
• There are two main types of isomerism: structural (or constitutional) isomerism and stereoisomerism.

Analysis and Detail

1. C6H5C≡NC6H5C≡N: This compound has a phenyl group attached to a cyano group (C≡N), and its structure suggests that it has functional groups that can allow for different arrangements.
2. C6H5 N→=CC6H5 N=→C: This compound has a similar phenyl and cyano attachment with a different connectivity.
3. The distinction between the connectivity of atoms in these compounds leads to the conclusion that they exhibit structural isomerism.

Verify and Summarize

Understanding that both compounds share the same molecular formula but differ in how the atoms are connected confirms they are structural isomers.

Final Answer

The compounds C6H5C≡NC6H5C≡N and C6H5 N→=CC6H5 N=→C exhibit structural isomerism.
