(a)
Interpretation:
All non-hydrogen atoms that are required to be in the same plane for Adenine are to be identified.
Concept introduction:
According to the VSEPR theory, if an atom is surrounded by three electron groups, either three bonds or two bonds and one lone pair, then the geometry of such an atom is trigonal planar, and thus, it must be
(b)
Interpretation:
All non-hydrogen atoms that are required to be in the same plane for Cytosine are to be identified.
Concept introduction:
According to the VSEPR theory, if an atom is surrounded by three electron groups, either three bonds or two bonds and one lone pair, then the geometry of such an atom is trigonal planar, and thus, it must be
(c)
Interpretation:
All non-hydrogen atoms that are required to be in the same plane for Guanine are to be identified.
Concept introduction:
According to the VSEPR theory, if an atom is surrounded by three electron groups, either three bonds or two bonds and one lone pair, then the geometry of such an atom is trigonal planar, and thus, it must be
(d)
Interpretation:
All non-hydrogen atoms that are required to be in the same plane for Thymine are to be identified.
Concept introduction:
According to the VSEPR theory, if an atom is surrounded by three electron groups, either three bonds or two bonds and one lone pair, then the geometry of such an atom is trigonal planar, and thus, it must be

- PLEASE ANSWER THE QUESTION!!!arrow_forward3. SYNTHESIS. Propose a sequence of synthetic steps (FGI) that convert the starting material (SM) into the Target molecule. For each FGI in your proposed synthesis, specify the reagents / conditions, and draw the product(s) of that FGI. DO NOT INCLUDE the FGI mxn in the answer you submit. If an FGI requires two reagent sets, specify the order in which the reagent sets are added, e.g., i) Hg(OAc)2 / H₂O; ii) NaBH4/MeOH. Indicate the stereochemistry (if any) of the products of each FGI. FGI 1. Me Starting Material Source of all carbons in the Target molecule (can use multiple copies) Me Me Target molecule + enantiomerarrow_forwardcurved arrows are used to illustate the flow of electrons. Using the provided starting and product structures, draw the curved electron-pushing arrows for the following reaction mechanism stepsarrow_forward
- At 90ºC the vapor pressure of ortho-xylene is 20 kPa and that of meta-xylene is 18 kPa. What is the composition of the vapor in equilibrium with a mixture in which the mole fraction of o-xylene is 0.60?arrow_forwardDraw the products of this reduction of a ketone with sodium borohydride. Use a dash or wedge bond to indicate the stereochemistry of substituents on asymmetric centers, where applicableIgnore any inorganic byproducts. 1) NaBH4 2) HCI/H2O Select to Drawarrow_forwardWhy do you think people who live at high altitudes are advised to add salt to water when boiling food like pasta? What mole fraction of NaCl is needed to raise the boiling point of H2O by 3˚C? Does the amount of salt added to water (typically about one teaspoon to four quarts of water) substantially change the boiling point? (Kb (H2O) = 0.51˚C/molal.)arrow_forward
