Why do we call a nucleophilic addition as 1 2 nucleophilic addition or 1 4 nucleophilic addition?

1,2-addition occurs when the carbonyl oxygen (1) is attached by the electrophile and the carbonyl carbon (2) attaches to the nucleophile
for the 1,4 the 4 is the beta carbon

What is the asnwer in addition?
An answer is a solution to a problem such as to answer to 1 + 1 is 2 and 2 is the answer or the sum in addition.
Comment Pyridine undergo nucleophilic and electrophilic substitution reaction?
Pyridine will add to carbon 3 in electrophilic reactions, such as Bromine addition. However in a nucleophilic reaction, such as seen in the Chichibabin reaction, carbon #2 and #4 are substituted such as if NH2 - attacked. Draw out the resonance forms and you will see this, or consult any Organic text under heterocyclic Chemistry.In a C3 attack, the electrophile will destabilize the C2 and C4 position, to a great extent since N lacks an octet in one of these resonance forms.In a nucleophilic addition, addition at C2 or C4 allows the negative charge to be shared by Nitrogen thus is preferred to the C3 attack.

What is the name of the numbers in a addition problem?

What is 1 million addition 1 thousand?

Example of associative law of addition?

What is -16 plus -2 equal?
-18
Is addition commutative explain?
Yes, because 1+2 and 2+1 have the same sum.
Is addition closed for negative one zero and one?
No, addition is not closed for -1, 0 and 1 because 1+1=2 and that is not one of the numbers you listed
