The pair of elements having largest partial charges should be identified. Concept Introduction: Ionic bond takes place between a metal and a nonmetal where ions having opposite charges are held by electrostatic attraction. If the difference in electronegativity between the atoms in a bond is 2.0 or more than 2.0, then it is an ionic bond. Covalent bond is formed when electrons are shared between atoms to form a bond. When the electronegativity between two atoms is similar, sharing of electron in the bond is equal and is called non-polar molecules. If the difference in electronegativity between the atoms in a bond is less than 0.5, then it is a nonpolar or covalent bond. While formation of a bond, there is a chance that electronegativity between the atoms are high. It tends to make the bond partially ionic and are called polar molecule. If the difference in electronegativity between the atoms in a bond is between 0.5 and 2.0, then it is a polar bond.

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
