Chemistry
1 answer:
Sidana [21]3 years ago
6 0

Explanation:

Quite a number of properties varies across a period. Some remains constant whereas others decreases.

As one moves from left to right;

  • The energy level remains the same.
  • The ionization energy increases progressively as a result of increasing nuclear charge.
  • Electron affinity increases from left to right.
  • Electronegativity increases.
  • Electropositivity decreases.

When warmed in dilute sulfuric acid, 1-phenyl-1,2-propanediol undergoes dehydration and rearrangement to give 2-phenylpropanal.
juin [17]

The mechanism is as suggested

1) Protonation of alcohol

2) removal of water molecule to give carbocation

3) hydride shift to give more stable carbocation [rearrangement]

4) the stability of carbocation due to resonance

5) removal of proton and formation 1-phenyl-1-propanone.

This is Pinacole pinacolone rearrangement

Thus the reaction can be depicted as

Calculate the volume of dry CO2 produced at body temperature (37 ∘
ra1l [238]
Using the equation PV = nRT
Therefore; V = nRT / P
Need moles of glucose converted to moles of the product gas (CO2).

Molecular weight calculation:
C 6 X 12.01 = 72.06
H 12 X 1.01= 12.12
O 6 X 16.00 = 96.00
 sum = 180.18
25.5 g of C6H12O6 ( 1 mol C6H12O6 / 180.18 g) ( 6 mol CO2 / 1 mol C6H12O6) = 0.84915 mol CO2 gas.
Convert temp: 37 °C + 273.15 = 310.15 K
V= ((0.84915 mol)× (0.0821 L atm / mol K) (310.15 K))/0.980 atm
 V = 22.0635 L
  = 22.06 L CO2
