Resonance effect in carboxylic acid​

Resonance decreases reactivity because it increases the stability of the molecule. The reason why resonance is decreasing the reactivity of the carboxylic acid is because moving the electrons causes the carbonyl carbon to become less partially positive (which makes the carboxylic acid more stable)

At 1:55, how is resonance decreasing reactivity? Kaplan book says that resonance in carboxylic acid derivates increases stability of the product which increases reactivity.

Resonance decreases reactivity because it increases the stability of the molecule. The reason why resonance is decreasing the reactivity of the carboxylic acid is because moving the electrons causes the carbonyl carbon to become less partially positive (which makes the carboxylic acid more stable). When you stabilize the carboxylic acid by making the carbonyl carbon less positive, you are decreasing its ability to be an electrophile in a reaction (in other words, you are making the molecule less reactive due to the increase in stability from the resonance).

Reactivity and stability are two opposing concepts. The more stable a molecule is, the less it wants to react. A decrease in stability results in an increase in reactivity and an increase in stability causes a decrease in reactivity. Think of it this way: a molecule always wants to be in it's most stable form. If it's not stable, it is going to want to react in order to stabilize itself. If it's already stable, it doesn't need to react.

explanation: well the force of an object when it lands sitting on the ground isthe force of a wide rage of situations crucial to physics? ; ( i 'm trying my best to alot but im not smart enofe you for giving me this chance though! 3(

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
