5 Jan

One thing,

With jaws strung with cords of slaver

and eyes sunken, blinking at the light, unfamiliar,

and drinking in the hollow victory,

Pasty, pointed, barking

Cocooned in sugar

Disguising horns and spines that find targets indiscriminately…

 

One thing, and another

that perches, ears pricked and nose prickling

on the beasty’s lap,

(hold your art history books to a mirror, ladies and gentlemen)

Oh its eyes glow with happiness

as its hair is brushed and threaded with ribbons.

Little puppy won’t cry tonight.

Not tonight.

 

One thing, and another, and another

that rears its cliché of an ugly head

and mixes itself a cocktail,

one part lime cordial to two parts self-doubt (or lemonade)

and sits and watches, not expecting

Anything At All

Probably isn’t even watching, too busy juggling or singing,

But whose fault might that be…

And is it a fault, or a design?

Something that was built with purpose and certainty,

Like a bridge, or a rocketbike.

Reversibility is a secondary trait.

 

One thing, and another, and another.

My iPod can destroy them all,

So I’ll stop worrying so much.

Hard Soft Acid Base Theory

20 Jun

Hypothetically held in your hot little hand
Is an acid or base you don’t quite understand.
To work out its properties quick as you please,
Close your eyes, hold your breath, and give it a squeeze.

It’s small like a marble and hard like a stone?
Its qualities suddenly make themselves known!
Its electron affinity is high as the sky
So it’s not as affected by charges nearby.

But what if it’s squishy like squashed up banana?
Its electrons are welcome to wander out farther.
A low oxidation, can be pulled out of shape,
These will suggest a soft acid or base.

So next time your looking for strong interactions,
Remember the fundamentals of attraction.
Like Pearson proposed, as a rough rule of thumb;
Hard to hard, soft to soft, and your work is done.

Chelate Effect

19 Jun

The chelate effect is dependent on size,
And clever young chemists, this will not surprise;
A five-membered ring is indeed the most stable,
More so if delocalisation enables
The flow of electrons through double bonds,
For resonance strengthens benzene hexagons.

But make that ring smaller, and lo and behold!
Ring strain will encourage the thing to unfold.
The more rings that bind to a metal cation,
The stronger the bonds the complex must rely on!
So, multiple five membered rings are the best
For a happy and stable metal complex.
