The given figure shows the distribution of molecular speeds of CO 2 and SO 2 molecules at 25 ° C . The curve for SO 2 and the curve which is comparable with the propane, a common fuel in portable grills is to be explained. Concept introduction: According to kinetic molecular theory postulates, Particles present in the gas have consistent and random motion. They collide with each other or the walls of their container. Particle present in gas have point masses with zero volume. The average kinetic energy of every gas particles is directly related to temperature. The speed of gas molecules increases with increase in temperature. Molecules having low molar mass will move faster than the molecules with high molar mass. A molecular weight is the sum of all the atomic weight of the atoms present in molecules. To determine: The curve for SO 2 and the curve which is comparable with the propane, a common fuel in portable grills.

How many signals do you expect in the H NMR spectrum for this molecule? Br Br Write the answer below. Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H atoms that would contribute to the same signal as the H already highlighted red. Note for advanced students: In this question, any multiplet is counted as one signal. Number of signals in the 'H NMR spectrum. For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in top molecule For the molecule in the bottom drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in bottom molecule

In the drawing area below, draw the major products of this organic reaction: 1. NaOH ? 2. CH3Br If there are no major products, because nothing much will happen to the reactant under these reaction conditions, check the box under the drawing area instead. No reaction. Click and drag to start drawing a structure. ☐ : A ค

Predict the major products of the following organic reaction: NC Δ ? Some important Notes: • Draw the major product, or products, of the reaction in the drawing area below. • If there aren't any products, because no reaction will take place, check the box below the drawing area instead. • Be sure to draw bonds carefully to show important geometric relationships between substituents. Note: if your answer contains a complicated ring structure, you must use one of the molecular fragment stamps (available in the menu at right) to enter the ring structure. You can add any substituents using the pencil tool in the usual way. Click and drag to start drawing a structure. Х а
