Which of the following bases is the STRONGEST? The base is followed by its Kb.A. C6H5NH2, 4.0 × 10-10 B. NH3, 1.76 × 10-5 C. CH3

Kamila [148]

Answer:

(D) (CH3CH2)2NH

Explanation:

In order to decide which base is strongest we need to calculate its PKb

PKb = -log [Kb]

A large Kb value and small PKb value gives the strongest base

Compound Kb PKb

(A) C6H5NH2 - 4 x 10^-10 9.349

(B) NH3 1.76x 10^-5 4.754

(D) (CH3CH2)2NH 8.6x 10^-4 3.066

(E) C5H5N 1.7x10^-9 8.77

Clearly (CH3CH2)2NH is the strongest base.

You are working in a laboratory, and you are given the task of converting cyclopentene into 1, 5-pentanediol. Your first thought

Helen [10]

Answer:

Reagent A = $H_3O^+$

Reagent B= $Na_2Cr_2O_7~H_2SO_4~H_2O$

Intermediate C= δ-Valerolactone

Explanation:

In the reaction from the alkene to the alcohol, we can use the alkene hydration in which the hydronium ion is added to the double bond followed by the attack of water to produce the alcohol.

Then in the conversion from alcohol to ketone can be produced if an oxidant reactive is used. In this case the Jones reagent ( $Na_2Cr_2O_7~H_2SO_4~H_2O$ ).

The intermediate is a structure produced by a peroxyacid. This reaction would introduce an ester group in the cycle generating the δ-Valerolactone (Figure 1).
