The terms
Concept introduction:
The total number of protons in an atom is said to be its atomic number. Atomic number is denoted by “Z”.
The total number of neutrons and protons of an atom is said to be its mass number. By using the total number of protons and neutrons all the atoms can be identified. Mass number is denoted by “A”.
An atom is always said to be neutral. Therefore for the charge to remain neutral the total number of electrons must be equal to total number of protons and hence, the atomic number is same as the total number of electrons.

EBK GENERAL CHEMISTRY: THE ESSENTIAL CO
- Problems: 1. Suggest a synthesis of amine (20), needed to study 135 whether cyclisation would occur during bromination of the double bond. NH2 (20)arrow_forwardDon't USE AIarrow_forwardShow the full mechanism of how the molecule ((1E, 3E, 5E)-1-methoxyhepta-1,3,5-triene) is built using substitution and elimination reactions. You can start with an alkane of any carbon length with any number of leaving groups attached or with a alkoxide of any carbon length (conjugate base of an alcohol). Show each step and and explanation for each reaction. Also include why the reagents and solvents were picked and what other products can be expected.arrow_forward
- Problems 1. Acids (11) and (12) were both made by Grignard addition to CO2 rather than by cyanide displacement (p T 80). Why? (11) -CO2H MeO- (12) CO,Harrow_forward2. Aldehyde (8) was needed for a butenolide synthesis. How would (8) be made?
