1(a). Chemists often use two different structures to represent a molecule of benzene, as shown below. structure
structure B
Describe, with the aid of suitable diagrams showing orbital overlap, the difference in bonding between structure A and structure B.
in your answer, you should use appropriate technical terms, spelled correctly.

Consider hydrogen in an excited state n = 5n=5 that emits photons to reach the ground state. there are various possible transitions other than straight to the ground state that can occur; for example, it can drop to the n = 3n=3 state followed by the n = 3n=3 to the ground state transition. which of the possible transitions will result in the emission of a photon in the visible region?
