Write bond-line formulas for four carboxylic acids with the formula C5H1002. Write bond-line formulas for three esters with the formula CSH1002.

Draw the Lewis structure for an isomer of C3H6O that is a ketone, and draw another Lewis structure for an isomer of C3H6O that is an aldehyde.

The normal pH range for blood plasma is 7.35–7.45. Under these conditions, would you expect the carboxyl group of lactic acid (pKa 3.08) to exist primarily as a carboxyl group or as a carboxylic anion? Explain.

Compounds Y and Z both have the formula C₂H18. Both Y and Z react with one molar equivalent of hydrogen in the presence of a palladium catalyst to form 2-methyloctane. The heat of hydrogenation of Y is less than that of Z. Y and Z each undergo hydroboration/oxidation to give a primary alcohol (OH attached to a primary carbon). What is the structure of Y? • In cases where there is more than one answer, just draw one. 1998) 0▾ + n [F ChemDoodle a

Structural formula for the four ketones with the molecular formula C6H12O.

A carboxylic acid reacts with water to form a carboxylate ion and H,O+. Complete the reaction. reaction: (CH),CHCH2COOH + H2O (CH), CHCH, COO¯ + H₂O+ Write the IUPAC name of the carboxylate ion formed in the reaction. IUPAC name: BIU X2 SPECIAL GREEK ALPHABET ~ I

Use the following information to answer the question A student added bromine solution to a hydrocarbon sample that contained an isomer of C6H12 (E) in the absence of light. After shaking the sample, the student noticed that the colour of the bromine solution changed from orange to colourless. 6. An interpretation that could be made from the student's observations is that the hydrocarbon sample is and the IUPAC name of the sample could be ii. I The statement above is completed by the information in row: Row i ii A saturated B saturated hex-2-ene cyclopentane C unsaturated hex-2-ene D unsaturated cyclopentane -12 markel

The disinfection of drinking water to control microbial contaminants can form chemical disinfection byproducts. These compounds result from the reaction of chlorine with naturally occurring organic matter (the dissolved molecules that give natural water the yellow-greenish color). One class of disinfection byproducts is the malodorous and unpalatable chlorophenols. 2,4-dichlorophenol is one compound of this class. a) Calculate the vapor pressure p*L of 2,4-dichlorophenol at 60 °C using Tb and structural information only OH .CI M, = 163.0 g/mol Tm = 43.7 °C Tp = 213.0°C %3D %3D %3D

Complete and balance the following combustion reactions. Assume that each hydrocarbon is converted completely to carbon dioxide and water. (a) Propane + O2 (b) Octane + O2 (c) Cyclohexane + O2 (d) 2-Methylpentane + O2

What is the meaning of the term tertiary (3) when it is used to classify alcohols? Draw a structural formula for the one tertiary (3) alcohol with the molecular formula C4H10O.
