Interpretation:
‘Energy state’ should be identified.
Concept introduction: The electron jumps from n=1 to n=2 is called the 1st excitation and n=2 to n=3 is 2nd excitation and like that. It is seen that as the number of n increases the energy gap between the successive orbitals decreases. The energy required to jump one electron from n=1 to n= infinity is called the ionisation energy of the atom.
The position of the electron on consumption of certain amount of energy is determined by Balmer-Rydberg equation, which is
Given:
The wave length (
To determine:
On absorption of ultra violet light at the ground state of wave length

- SH 0arrow_forward2. Please consider the two all 'cis' isomers of trimethylcyclohexane drawn below. Draw the two chair conformers of each stereoisomer below (1 and 2) and calculate their torsional interaction energies in order to identify the lower energy conformer for each stereoisomer. Based on your calculations, state which of the two stereoisomers 1 and 2 is less stable and which is more stable. [1,3-diaxial CH3 CH3 = 3.7kcal/mol; 1,3-diaxial CH3 H = 0.88kcal/mol; cis-1,2 (axial:equatorial) CH3 CH3 = 0.88kcal/mol; trans-1,2-diequatorial CH3 CH3 = 0.88kcal/mol) all-cis-1,2,3- 1 all-cis-1,2,4- 2arrow_forwardNonearrow_forward
