Neutrons as well as electrons and x-rays can be used to obtain information about molecular structure through diffraction patterns. What must the velocity of a neutron be for its de Broglie wavelength to be about five times smaller than a bond length? How does this velocity compare (bigger, smaller, or the same) if electrons were diffracted? A typical bond length for C-C is 1.54Å (1.54 x 10-1ºm).arrow_forwardO TE1ll Vol) 13:56 Question 3: What is the best reason for the observation that carbon can form four bonds and no more? * Carbon is in period 2 of the periodic table. Carbon has four valence electrons in the n = 2 energy level. An electron is transferred from the filled 2s orbital to an unoccupied 2p orbital. The energy gap between the n = 1 and n = 2 is large and no further electrons can, therefore, be promoted from lower energy levels to facilitate more bonds. All of the reasons given above explain the observation. Question 4: Select the structures in Figure 4 that are drawn correctly * II ...arrow_forward
