Dr. Daniel discovered three new saturated hydrocarbon compounds (compounds A,B, and C) and wanted to determine their physical and chemical properties. Compound A and B are optically inactive and vice versa for compound C. When these three compounds undergoes oxidation process, it gives negative results. Besides, it also not decolorize the bromine water during chemical reaction. i. Draw the possible skeletal formula for compounds A and B containing at least two substituents.  ii. Draw the line-wedge-dash-projection based on diastereomer of compound C and label their optically active site . iii. Identify the IUPAC nomenclature name for compounds A, B and C. Label the carbon and hydrogen classification for compounds A, B, and C. iv. List two (2) physical properties and two (2) chemical properties for compounds B. v. Discuss the sequence of compounds A, B, and C according to their boiling point. vi. Predict the complete chemical reaction for the combustion of compound B

11. Consider the line-angle formulas shown here and answer the questions. (ii) (iii) (iv) a. Which pair of formulas represents isomers? Draw each structure. b. Which formula represents an alkyl halide? Name the compound and write its condensed structural formula. c. Which formula represents a cyclic alkane? Name the compound and draw its structure. d. What is the molecular formula of the compound represented by (i)?
