Answer:
CH₃CH₂CH₂COOH > CH₃CH₂COOH > ClCH₂CH₂COOH > ClCH₂COOH
Explanation:
Electron-withdrawing groups (EWGs) increase acidity by inductive removal of electrons from the carboxyl group.
Electron-donating groups (EDGs) decrease acidity by inductive donation of electrons to the carboxyl group.
- The closer the substituent is to the carboxyl group, the greater is its effect.
- The more substituents, the greater the effect.
- The effect tails off rapidly and is almost zero after about three C-C bonds.
CH₃CH₂-CH₂COOH — EDG — weakest — pKₐ = 4.82
CH₃-CH₂COOH — reference — pKₐ = 4.75
ClCH₂-CH₂COOH — EWG on β-carbon— stronger — pKₐ = 4.00
ClCH₂COOH — EWG on α-carbon — strongest — pKₐ = 2.87
Answer: 1. h oxidized, 2. g reduced, 3. e glucose, 4. c pyruvate, 5. b NAD+, 6. a NADH.
Explanation:
Glycolysis is also known as Embden-Meyerhof pathway, and in this process one mole of glucose is oxidised into two moles of pyruvate in a series of enzyme-catalyzed reaction and do not involve molecular oxygen i.e. oxygen indepenedent process. This process is studied in two phases preparatory (energy-investment) and pay-off phase(energy generation).
Net reaction: Glucose + 2NAD+ HPO4-2 = 2 Pyruvate + 2NADH + 2ATP + 2H2O.
<u>( I) Bonds are broken, and the reaction is endothermic.</u>
(2) Bonds are broken , and the reaction is exothermic.
(3) Bonds are formed, and the reaction is endothermic.
