The most likely m / z values for the base peak in the mass spectrum of 3-methylpentane has to be given. Concept introduction: Interpreting a mass spectrum: 1. The each m/z values is the m/z value of one the fragments to the nearest whole number. 2. The peak with the highest m/z value in the molecular ions (M + ), the fragment that results when the molecules lose an electrons as result of being bombarding by the electron beam. 3. The m/z value of the molecular ion gives the molecular mass of the compound. 4. Peaks with smaller m/z values, fragment ion peak represent positively charged fragments of the molecular ion. Base peak of mass spectrum: The base peak is the one of highest (or) tallest peak, it has great abundance. It has the greatest relative abundance because it is generally the most stable positively charged fragment. Percentage of base peak: The base peak is assigned a relative abundance (RA) of 100% and the relative abundance of each other peaks is respective mass spectrum percentage of base peak. For example the weak bonds break in preference to strong bonds and bonds that break to form more stable fragments break in performance to those that form less stable fragments.

Interpretation Introduction

Interpretation:

The most likely m/z values for the base peak in the mass spectrum of 3-methylpentane has to be given.

Concept introduction:

Interpreting a mass spectrum:

1. The each m/z values is the m/z value of one the fragments to the nearest whole number.

2. The peak with the highest m/z value in the molecular ions (M⁺), the fragment that results when the molecules lose an electrons as result of being bombarding by the electron beam.

3. The m/z value of the molecular ion gives the molecular mass of the compound.

4. Peaks with smaller m/z values, fragment ion peak represent positively charged fragments of the molecular ion.

Base peak of mass spectrum: The base peak is the one of highest (or) tallest peak, it has great abundance. It has the greatest relative abundance because it is generally the most stable positively charged fragment.

Percentage of base peak: The base peak is assigned a relative abundance (RA) of 100% and the relative abundance of each other peaks is respective mass spectrum percentage of base peak. For example the weak bonds break in preference to strong bonds and bonds that break to form more stable fragments break in performance to those that form less stable fragments.

PLEASE READ!!! I DONT WANT EXAMPLES, I DONT WANT WORDS OR PARAGRAPHS FOR THE MECHANISM!!! THANKS First image: QUESTION 6. I have to show, with ARROWS and STRUCTURES, the mechanism of the reaction at the bottom. Also I have to show by mecanism why the reaction wouldn't work if the alcohol was primary. I also tried to draw the mechanism, tell me what to change. Please note that its an AMIDE thats formed not an AMINE the nitrogen has ONE hydrogen and one Phenyl-C-Phenyl. I already asked for this mechanism and got as a final product ...-NH2 not whats shown on the picture, thank you Ths second part. QUESTION 3. I just need a way to synthesize the lactone A, I already started please continue from where I left it Second image: I simply need the products, substrates or reagents, thank you
