6) (10pts) Use the Lewis dot structure of adenosine, one of the nucleic acid bases (A...
1. Draw the Lewis structure of water showing all valence electrons with lines for covalent bonds and dots for unshared electrons. Add a box around each hydrogen- bonding donor site and add a circle around any hydrogen- bonding acceptor sites in your structure. (Hint: there are two of each. The equal number of donors and acceptors is why water hydrogen-bonds so well with other waters.) Draw the Lewis structure of hydrofluoric acid, HF, showing all valence electrons with lines for...

11. Fill in the Lewis dot symbols for H, C, N, O, and Cl in the table. Based on this information, predict how many bonds and how many lone pairs each of these atoms will possess. Element Lewis Dot Symbol Bonds Lone Pairs H' Hydrogen Carbon Nitrogen Oxygen Chlorine
1. For each compound, draw the Lewis dot structure, the number of lone pairs, and the number of electronic groups for the central atom. Each Lewis dot structure follows the octet rule: hydrogen has one bond, all other atoms are surrounded by a total of eight electrons. Each covalent bond counts as we clectrons. Each nonbonded pair of electrons (lone pairs) count as two electrons. The number of nonbonded electrons is how many electrons from the central atom are not...
Below are bases used in nucleic acids. (a) why are they called bases-what allows them to act as a base? (b) the two strands of DNA are held together in the double helix form by hydrogen bonds between complementary base pairs. What is a hydrogen bond? (c) Suppose a new disease appears that creates covalent, rather than hydrogen, bonds between the two strands of DNA (this is VERY unlikely!). If you had to design a drug to combat the disease,...
Lewis Dot Structures describe the connectivity of the atoms in a species. a) Determine the central atom (least electronegative) Hydrogen will not be a central atom. b) Draw the skeleton. c) Determine the total number of valence shell electrons d) Place the electrons around the terminal atoms to satisfy the octet rule (Be). Hydrogen ok with two electrons. If there are electrons left over then place them around the central atoms as lone pair electrons. Some atoms (period 3 and...
- 2014 1. Using only the periodic table, determine the Lewis Dot structure of the following b) •Se c) • Mg2+ 2. What type of force holds together ionic bonds?_ 3. Why should two atoms share electrons? 4. Classify the following bonds as ionic, polar covalent, or covalent: (a) the bond in HCI (b) The bond in KF (c) the CC bond in H3CCHz Draw the skeletal structure of SiCl4 and answer the following questions. a. How many total valence...
III. Additional Questions 1. For hydrazine, N,H a) Draw the Lewis Structure. Hint: the two nitrogen atoms are bonded to each other, and each nitro- gen atom is bonded to two hydrogen atoms. b) Determine the EDG and MG for each nitrogen atom. c) Approximate the bond angles around each nitrogen atom. a) H-N--H H H b) EDG MG
Using a partial Lewis dot structure like the one shown above, draw two more possible structures for the radical cation below and circle the missing electron. Fragmentation of Alkanes loss of e wadol C6H14 radical cation = (M+. The scheme above shows the formation of the hexane radical cation from the neutral hexane molecule by bombarding the molecule with high energy electrons which results in the loss of an electron from the molecule. The species that is missing one electron...
