iv only

Text Solution

Verified by Experts

The correct Answer is:

Chrophyll a is the primary photosynthetic pigment, which is blush green in the pure state. It has an empirical formula of `C_(55)H_(72)O_(5)N_(4)Mg` and molecular weight of 893. It absobs more red wavelength of light than violet blue. It is soluble in a number of organic sovlents such as petroleum ether.

An electron in a hydrogen atom is excited from the ground state to the n = 4 state. Predict which of the following statements are true or false : (i) n = 4 is the first excited state. (ii) It takes more energy to ionize (remove) the electron from n = 14 than in the ground state. (iii) The wavelength of light emitted when the electron drops from n = 4 to n = 2 is longer than that from n = 4 to n = 1 . (iv) The wavelength which the atom absorbs in going from n = 1 to n = 4 is the same as emitted when it goes from n = 4 to n = 1 . (v) The electron is farther from the nucleus (on average) in n = 4 than in the ground state.
