Chapter 5 - How Much, How Fast & How Far?

Heterolytic fission is like that moment when two friends share a chocolate bar, but one grabs both pieces. When a covalent bond breaks, and one atom hogs both electrons, it&#39;s heterolytic fission!

<ul>
	<li>Unsymmetrical Split: One atom gets both electrons, while the other gets none.</li>
	<li>Result: Formation of a cation (electron deficit, feels left out 🙁) and an anion (extra electron, feeling greedy 🤑).</li>
</ul>

&nbsp;

Imagine drawing a slide, where electrons slide from one atom to another! This slide is represented by a double-barbed curly arrow.

<ul>
	<li>
	Think of halogenoalkanes like a group of friends at a dance party. When their favorite song (heterolytic fission!) comes on, one of them (halogen) exits the dance floor, taking both dance moves (electrons) with them! The left-behind buddy (alkyl group) becomes positively charged (as they&#39;ve lost their moves).

	Example: Bromomethane 💃

	Step 1: Imagine bromomethane as a duo - a bromine (Br) and a carbon atom (C) dancing together.

	Step 2: Suddenly, bromine decides to go solo and takes both of the shared dance moves (electrons).

	Step 3: The dance floor is now left with a solo, positively charged carbon dancer called a methyl carbocation and a bromine dancer with extra moves called a bromide anion.
	</li>
</ul>

🤓 Did you know? The species formed in this dance breakup (heterolytic fission) don&rsquo;t stay solo for long. They&#39;re like the life of the party but quickly exit to join another dance! They&#39;re unstable and usually intermediates in a reaction.

<ul>
	<li>Radicals: This is like a friend duo breaking up but deciding to split their shared chocolate bar evenly. Each friend (atom) gets one piece (electron).</li>
	<li>
	Nucleophilic Substitution Reactions: It&rsquo;s the heterolytic fission dance! One atom takes both moves (electrons) and goes solo, while the other is left feeling positive and awaiting a new partner.
	</li>
</ul>

Heterolytic fission is the unsymmetrical breaking of a bond, with one atom running off with both electrons. It results in a cation and an anion, and it&#39;s like a dance where one dancer takes all the moves!
