Draw the curved arrow mechanism for the addition of HCN in water with NaOH to heptan-4-one to give the corresponding cyanohydrin

in the fewest steps. Draw the arrows that lead to the resonance structures with full octets around each atom other than hydrogen. Draw all electrons and charges if necessary on all structures; do not show any inorganic side products or counterions. Reagents needed for each step are provided in the boxes.

Answer:

Cyanohydrin is formed through nucleophilic addition of cyanide ion to carbonyl center of the given ketone

Explanation:

  • NaOH maintains basic medium. Hence dissociation of HCN gets favored to produce nucleophile CN^{-}
  • In first step, CN^{-} is produced through dissociation of HCN.
  • In second step, CN^{-} gives nucleophilic addition at the cabonyl center of heptan-4-one,
  • In the third step, protonation of negatively charged oxygen atom occurs leading to formation of cyanohydrin.
  • Full reaction mechanism has been shown below.

If a frog initially contained 2 grams of carbon-14 and the half-life of carbon-14 is 5,730 years, how much carbon-14 remains in
andreyandreev [35.5K]
Half life is the time taken for a radioactive isotope to decay by half its original mass. In this case the half life of carbon-14 is 5.730 years. 
Using the formula;
New mass = original mass × (1/2)^n; where n is the number of half lives (in this case n=1 ) 
New mass = 2 g × (1/2)^1     
                  = 1 g
Therefore; the mass of carbon-14 that remains will be 1 g

The second-order rate constants for the reaction of oxygen atoms witharomatic hydrocarbons have been measured (R. Atkinson and J
Pepsi [2]

Answer:

A = 1,13x10¹⁰

Ea = 16,7 kJ/mol

Explanation:

Using Arrhenius law:

ln k = -Ea/R × 1/T + ln(A)

You can graph ln rate constant in x vs 1/T in y to obtain slope: -Ea/R and intercept is ln(A).

Using the values you will obtain:

y = -2006,9 x +23,147

As R = 8,314472x10⁻³ kJ/molK:

-Ea/8,314472x10⁻³ kJ/molK = -2006,9 K⁻¹

<em>Ea = 16,7 kJ/mol</em>

Pre-exponential factor is:

ln A = 23,147

A = e^23,147

<em>A = 1,13x10¹⁰</em>

<em></em>

I hope it helps!
