To explain and clarify the difference between atomic number and mass number. Concept Introduction: The atomic symbol notation is as follows: Atomic number, Z Mass number, A Atomic Symbol Charge , + / − Here A = mass number which is equal to the total number of protons + number of neutrons, Z= atomic number of any element which is also indicates Number of protons or number of electrons in the given atom. The charge of an ion is showed by + or − sign on the right-side super script. The atoms of same element with different mass number or atomic mass are called isotopes.

Question

81. a. Propose a mechanism for the following reaction: OH CH2=CHCHC=N b. What is the product of the following reaction? HO H₂O N=CCH2CH2CH OH HO CH3CCH=CH2 H₂O C=N 82. Unlike a phosphonium ylide that reacts with an aldehyde or a ketone to form an alkene a sulfonium ulia

Question

Chapter 4, Problem 89AP

Interpretation Introduction

Interpretation: To explain and clarify the difference between atomic number and mass number.

Concept Introduction: The atomic symbol notation is as follows:

Atomic number, ZMass number, AAtomic SymbolCharge, +/−

Here A = mass number which is equal to the total number of protons + number of neutrons, Z= atomic number of any element which is also indicates Number of protons or number of electrons in the given atom.

The charge of an ion is showed by + or − sign on the right-side super script.

The atoms of same element with different mass number or atomic mass are called isotopes.

For each reaction below, decide if the first stable organic product that forms in solution will create a new CC bond, and check the appropriate box. Next, for each reaction to which you answered "Yes" to in the table, draw this product in the drawing area below. Note for advanced students: for this problem, don't worry if you think this product will continue to react under the current conditions - just focus on the first stable product you expect to form in solution. ?

Predicting As the lead product manager at OrganometALEKS Industries, you are trying to decide if the following reaction will make a molecule with a new C - C bond as its major product: H₂N O H 1. ? 2. H3O+ If this reaction will work, draw the major organic product or products you would expect in the drawing area below. If there's more than one major product, you can draw them in any arrangement you like. Be sure you use wedge and dash bonds if necessary, for example to distinguish between major products with different stereochemistry. 0 If the major products of this reaction won't have a new CC bond, just check the box under the drawing area and leave it blank. فا Explanation Check Click and drag to start drawing a structure.
