a) CH3CH(NH2)COOH
b) CH2(NH2)COOH
c) CH2(OH)CN(NH2)COOH
Q2.Identify the functional groups in each of the following molecules:
a) CH3CH2COCH2CH2CH3
b) CH3COOC2H5
c) CH3CH2OCH2CH2CH2CH3
Q3. How many liters of air (78% N2, 22% O2 by volume) at 20 degrees celcius and 1.00 atm are needed for the complete combustion of 1.0 L of octane, C8H18, a typical gasoline component that has a density of 70 g/mL?
Q4. Isopropanol is prepared by reacting propylene (CH3CHCH2) with sulfuric acid, followed by treatment with water.
a) show the sequence of steps leading to the product. What is the role of sulfuric acid?
b) draw the structure of an alcohol that is an isomer of isopropanol.
c) Is isopropanol a chiral molecule?
d) what property of isopropanol makes it useful as a rubbing alcohol?
Q5. Under conditions of acid catalysis, alkenes react with water to form alcohols. As in the case with hydrogen halides, the addition reaction in the formation of alcohols is also governed by Markovnikov's rule. An alkene of approximate molar mass of 42g reacts with water and sulfuric acid to produce a compound that reacts with acidic potassium dichromate solution to produce a ketone. Identify all the compounds in the preceding steps.
Provide complete and step by step solution for the question and show calculations and use formulas.
