intermediates

[Mallika Singh 1G]

where exactly do the intermediates (which cancel out) come from?

[DarrenKim_1H]

Not sure exactly what you mean. Reaction intermediates are formed from one reaction, like any other part of the equation and then completely consumed in the following reaction

[Justin Seok 2A]

Intermediates are a necessary part of the reaction, as the reactants don't necessarily just form into the products in one step so intermediates are formed and used up within reactions. However, they do not show up in the products.

[Rory Simpson 2F]

Intermediates are any species that are initially formed at some step in the reaction and then are consumed entirely in the reaction process. So, they won't be in the final products but they will be apparent if you write out all of the steps of the reaction.

[Nuoya Jiang]

It is first formed as a product and then a reactant in the reaction.

[Lauren Stack 1C]

In a multi-step reaction, there are intermediates. They are something that forms in an earlier step, but are ultimately used as a reactant in a subsequent step. Thus, they are cancelled out in the net/final equation. They are essential to the mechanism of the reaction, but do not end up in the final equation.

[CNourian2H]

Think about them as something necessary to get from the reactants you want to products you want. they come along in process, but arent part of initial reactants or final products.

[Edmund Zhi 2B]

Reaction intermediates are formed but are consumed later on to produce the actual products and are therefore not part of the net overall reaction

[Indy Bui 1l]

Intermediates are what they sound like. They are molecules that are produced in one reaction and consumed by a second reaction. They occur, because most reactions don't always happen in a single step. Intermediates just represent products in a first reaction and reactants in a second. You can tell, because they are used up.
