1. $(0.4\mathrm{pt})$ Give the molecular formula (e.g. ${\mathrm{C}}_6{\mathrm{H}}_{12}{\mathrm{O}}_6$ ) for the following compound. What is the hybridization (e.g. ${\mathrm{sp}}^3$ ) of the indicated atom? 2. $(0.3\mathrm{pt})$ Draw a valid structure with no formal charges for a molecule with the formula ${\mathrm{C}}_5{\mathrm{H}}_{11}$ NO. Include lone pairs of electrons if there are any. 3. $(0.2\mathrm{pt})$ Draw the skeletal structure (like the structure in Question 1) for ${\mathrm{CH}}_3{\mathrm{CH}}_2{\mathrm{OCOC}}_6{\mathrm{H}}_5$. 4. $(0.5\mathrm{pts})$ Draw the structure of $(3S,4R)$-4-chloroheptan-3-ol showing proper stereochemistry of chiral centers by using wedge and dashed bonds.
