Question

determine the relationship between structure a and structure b in each row of the table.

structure a	structure b	relationship

• resonance structures
• neither |

$h - c^+ - n - (ch_3)_2$

$h_3c - c^+ - n - h_2$

- isomers

• resonance structures
• neither |

$h_3c - c^+ - n≡n:$

$:n≡n^+ - c - h_3c - h$

- isomers

• resonance structures
• neither |

Explanation:

1. For the first pair: Isomers have the same molecular formula but different connectivity or spatial arrangement. Resonance structures are different Lewis - structure depictions of the same molecule with the same connectivity but different electron distributions. The first pair has different connectivities of atoms, so they are isomers.
2. For the second pair: They have different connectivities of atoms, so they are isomers.
3. For the third pair: They have different connectivities of atoms, so they are isomers.

Answer:

1. Isomers
2. Isomers
3. Isomers
