Chapter 4, Problem 8PE

(a)

Interpretation Introduction

Interpretation:

The disappearance of sucrose in a beaker and the clear solution in the beaker is a physical or chemical property has to be given.

Concept Introduction:

Physical properties:

Physical properties can be observed or measured without changing the composition of matter.  Physical properties are used to observe and describe matter.

Chemical properties:

Chemical properties are only observed during a chemical reaction and thus changing the substance chemical composition.

(b)

Interpretation Introduction

Interpretation:

A copper statue over a time turns green is a physical or chemical property has to be given.

Concept Introduction:

Refer to part (a).

(c)

Interpretation Introduction

Interpretation:

The volume of bubbles produced when a teaspoon of baking soda added to vinegar is a physical or chemical property has to be given.

Concept Introduction:

Refer to part (a).

I have a question about this problem involving mechanisms and drawing curved arrows for acids and bases. I know we need to identify the nucleophile and electrophile, but are there different types of reactions? For instance, what about Grignard reagents and other types that I might not be familiar with? Can you help me with this? I want to identify the names of the mechanisms for problems 1-14, such as Gilman reagents and others. Are they all the same? Also, could you rewrite it so I can better understand? The handwriting is pretty cluttered. Additionally, I need to label the nucleophile and electrophile, but my main concern is whether those reactions differ, like the "Brønsted-Lowry acid-base mechanism, Lewis acid-base mechanism, acid-catalyzed mechanisms, acid-catalyzed reactions, base-catalyzed reactions, nucleophilic substitution mechanisms (SN1 and SN2), elimination reactions (E1 and E2), organometallic mechanisms, and so forth."
