Interpretation Introduction

Interpretation:

The number of atoms of the element X left after 1.0 hour from the given sample is to be determined.

Concept Introduction:

The half-life of a substance is the numerical value in which the amount of the given radioactive substance is reduced to half of the initial value. The half-life for a given substance is represented by t1/2.

After each half-life period, the amount of the substance is reduced to half of the initial value.

One hour is equal to 60 minutes.

show the retrosynthesis of this molecule step by step starting with 1,3-dimethoxy benzene H3CO OH OH OCH 3
Consider the reaction of a propanoate ester with hydroxide ion shown below. A series of four alcohol leaving groups were tested to determine which would be the best leaving group. Based on the pKa values of the alcohols, predict which alcohol would produce the fastest hydrolysis reaction. HO FOR A Alcohol I, pKa =16.0 B Alcohol II, pKa =10.0 C Alcohol III, pKa = 7.2 + ROH D Alcohol IV, pKa = 6.6
