## CH2=CH-CH=CH-CH=CH2 The image shows a series of equations and calculations related to the molecule CH2=CH-CH=CH-CH=CH2. **1. Calculating the bond length of the molecule:** * 3 x 134 pm = 402 pm * 2 x 154 pm = 308 pm * 154 pm + 134 pm = 154 pm * a = 864 pm **2. Calculating the energy levels of the molecule using the following equation:** * E^n = (n^2 * h^2) / (8 * m * a^2) * The calculations are shown for n = 1, n = 2 and n = 3 **3. Diagram of the energy levels:** * The diagram shows four energy levels labeled E1, E2, E3 and E4. * There are arrows indicating how the electrons can transition between levels, with transitions to higher levels requiring the absorption of energy. **Equation 6:** * N ≤ (a^2) / (8*m*a^2) The image is also of a hand holding a piece of paper, it is not clear what the text on this paper says, or what the relationship between the two is.
