Interpretation Introduction

Interpretation:

The amount of I-131 left after 32 days is to be determined.

Concept Introduction:

The time required by a radioactive sample to decompose to half of its mass is called its half-life.

In every half-life, the sample is reduced to half of its mass that was taken initially in the current decay.

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
