Surname 1 Your name Professor’s name Date Course Bonding 1. Define the word molecule using the words atoms and bond. A molecule refers to a group of atoms that are bonded together, which forms the smallest unit of a chemical compound that takes part in a given chemical reaction. In other words, molecules are composed of atoms which around bound together by chemical bonds. 2. How many electrons would you expect between the C and O atoms joined with a double covalent bond (also called a “double bond”) in Figure 2.1? 4 electrons between carbon and oxygen bonded by the double bond. 3. In the molecule glycine shown in figure 2.1, there are two different carbon atoms. The structure has been re-drawn below and the carbons labeled. a. How many bonds are being made with each of the two carbon atoms? i.e. How many bonds are being made with carbon 1; with carbon 2? Each carbon "1" is surrounded by 4 bonds, and carbon "2" is also surrounded by 4 bonds. b. How many electrons are represented by the bonds surrounding each individual carbon atom? 8 electrons(=4bonds x 2electrons) are surrounded by each carbon atom 1 and 2. 4. The NaCl does not have a covalent bond – i.e. there is no sharing of electrons. – rather it has an ionic bond. What seems to be holding the NaCl (i.e. table salt) molecule together? Electrostatic force present between opposite charges of Na+ and Cl- in NaCl. 5. In Figure 2.4, why is there only one electron in the blue box drawn around the hydrogen? Please in ...
