Chapter 6, Problem 49P

(a)

Interpretation Introduction

Interpretation:

The given compound should be prepared using alkene and other reagents.

Concept Introduction:

Addition ofH2:

Catalytic hydrogenation in presence of Pd/C is an example for syn addition of hydrogen.

Essential Organic Chemistry, Global Edition, Chapter 6, Problem 49P , additional homework tip  1

For cyclic reactants, the addition of H2 will form cis enantiomers since two hydrogens adds to one side of the double bond.

Enantiomers: they are chiral molecules whose mirror images are not superimposable.

Enantiomers are given configuration as R or S based on the atoms bonded with chiral (carbon bonded with four different substituents) carbon.

Carbocation: carbon ion that bears a positive charge on it.

Carbocation stability order:

Essential Organic Chemistry, Global Edition, Chapter 6, Problem 49P , additional homework tip  2

Nucleophile: It donates pair of electrons to positively charged substrate resulting in the formation of chemical bond.

Electrophile: It is positively charged species which seeks for negative charge and hence accepts pair of electrons from negatively charged species (Nucleophiles) which results in the formation of chemical bond.

(c)

Interpretation Introduction

Interpretation:

The given compound should be prepared using alkene and other reagents.

Concept Introduction:

Addition of hydrogen halides:

In the addition of hydrogen halides over alkenes, first the H+ gets bonded to carbon and forms most stable carbocation which then the halide ion bonds with carbocation that results in formation of product.

(ME EX1) Prblm #9/10    Can you explain in detail (step by step) I'm so confused with these problems. For turmber 13 can u turn them into lewis dot structures so I can better understand because, and then as well explain the resonance structure part. Thanks for the help.
Problems 19 and 20: (ME EX1) Can you please explain the following in detail? I'm having trouble understanding them. Both problems are difficult for me to explain in detail, so please include the drawings and answers.
(ME EX1) Prblm #4-11 Can you please help me and explain these I'm very confused in detail please. Prblm number 9 I don't understand at all (its soo confusing to me and redraw it so I can better depict it).
