(a)
Interpretation:
Whether the form of the Fischer projection of the molecule is D or L is to be identified. The structure of the enantiomer is to be drawn.
Concept introduction:
The D (dextrorotatory) and L (laevorotatory) isomers are mirror images of each other and are known as enantiomers. The enantiomers which have the property of rotating the plane polarized light to the left are laevorotatory and those which rotate the plane polarized light to the right are dextrorotatory. Therefore, the characteristic physical property of optically active molecules is rotating plane polarized light.

- Explain what characteristics of metalloids are more like metals and which are more like nonmetals, based on Na, Mg, Fe, Cl, and Ar.arrow_forwardplease solve this, and help me know which boxes to check. Thank you so much in advance.arrow_forwardElectronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. Describe how electronegativity is illustrated on the periodic table including trends between groups and periods and significance of atom size.arrow_forward
- Define the term “transition.” How does this definition apply to the transition metals?arrow_forwardDescribe how the properties of the different types of elements (metals, nonmetals, metalloids) differ.arrow_forwardUse a textbook or other valid source to research the physical and chemical properties of each element listed in Data Table 1 using the following as a guideline: Ductile (able to be deformed without losing toughness) and malleable (able to be hammered or pressed permanently out of shape without breaking or cracking) or not ductile or malleable Good, semi, or poor conductors of electricity and heat High or low melting and boiling points Occur or do not occur uncombined/freely in nature High, intermediate, or low reactivity Loses or gains electrons during reactions or is not reactivearrow_forward
- Provide the Physical and Chemical Properties of Elements of the following elements listedarrow_forwardQuestions 4 and 5arrow_forwardFor a titration of 40.00 mL of 0.0500 M oxalic acid H2C2O4 with 0.1000 M KOH, calculate the pH at each of the following volume of KOH used in the titration: 1) before the titration begin;2) 15 mL; 3) 20 mL; 4) 25 mL; 5) 40 mL; 6) 50 mL. Ka1 = 5.90×10^-2, Ka2 = 6.50×10^-5 for oxalic acid.arrow_forward
