orgonic chemistry 9A. An optically active compound (A), C6H10, reacts with H2,Pd/C to produce compound (B),...
Organic Chemistry II Question 3: Compound B has the molecular formula of C6H10 and gives (CH3)2CHCH2CH2CH3 when treated with excess H2 in the presence of Pd. B reacts with NaNH2 and CH3I to form compound C that has the molecular formula C7H12. Give the structures for B and C.
Compound A is a D-aldopentose that can be
oxidized to an optically active aldaric acid B. On
Kiliani-Fischer chain extension, A is converted
into C and D; C
can be oxidized to an optically inactive aldaric acid
E, but D is oxidized to an
optically active aldaric acid F.
What is the structure of compound C?
PLEASE SPECIFY WHAT IS COMPOUND C
Also please take into account the instructions for the answer
shown
Compound A is a D-aldopentose that can...
An aldopentose A, is oxidised to a diacid, B, which is optically active Compound A is also degraded to an aldotetrose, C, which undergoes oxidation to an optically inactive diacid D. Given that A has the D configuration what are the structures of A through to D? Justify your answers.

2 (8 marks). Optically active compound 1 of molecular formula C6H12 was treated with CH212 over Cu(Zn) to give compound 2 which was also optically active. Later it was found that reaction of (R)-3-cyclopropylbut-1-ene with H2 over a Pd/C catalyst also gave compound 2. (a) What is the degree of unsaturation of compound 1? (b) In the boxes on the answer sheet, draw clear skeletal (line-bond) structures of compound 1 and compound 2. Note - no credit will be given...
CH3 CH3 Н3С- H2, Pd/C CH3 optically active diterpene mixture of diastereomers 1)О. 2) ZnvНОАс H3C Нас сH3 + о + о + Hн H3C
eference Compound A, CH,60, was found to be an optically active alcohol. Despite its apparent unsaturation, no hydrogen was absorbed on catalytic reduction over a Pd/C eatalyst. On treatment of A with dilute H,SO dehydration occurred and an optically inactive alkene B, CH14 was produced as the major product. Alkene B, on ozonolysis, gave two products. Product C, C-H,0, was shown to be an aldehyde while product D, CH,O, was shown to be a ketone. Draw the structure of compound...
An optically active alkyne A (C10H14) can be catalytically hydrogenated to butylcyclohexane. Treatment of A with C2H5MgBr liberates no gas. Catalytic hydrogenation of A over Pd/C in the presence of quinoline poison and treatment of the product B with O3 and then H2O2 gives an optically active tricarboxylic acid C8H12O6. (A tricarboxylic acid is a compound with three –CO2H groups.) Give the structure of A (without stereochemistry).
All of the following nonosaccharldes are optically active. Which one, on reductrion with H_2/Pd, gives a product that is not optically active? Which bond has the greatest polarity?

Extra Credit An unknown compound A of molecular formula of C10H180 reacts with H2SO4 and heat to form two compounds (B and C) of molecular formula C10H16. B and C both react with H2 over Pd/C to form decalin. Ozonolysis of B forms D, and ozonolysis of C forms a diketone E of molecular formula C10H1602. Identify the structures of A, B, C and E. decalin
