Alkene
In organic chemistry, an alkene is an unsaturated hydrocarbon that contains at least one carbon–carbon double bond. Alkene, olefin, and olefine are used often interchangeably (see nomenclature section below). Acyclic alkenes, with only one double bond and no other functional groups, known as mono-enes, form a homologous series of hydrocarbons with the general formula CnH2n. Alkenes have two hydrogen atoms less than the corresponding alkane (with the same number of carbon atoms). The simplest alkene, ethylene (C2H4), which has the International Union of Pure and Applied Chemistry (IUPAC) name ethene is the organic compound produced on the largest scale industrially.Aromatic compounds are often drawn as cyclic alkenes, but their structure and properties are different and they are not considered to be alkenes.
Structure
Bonding
Like a single covalent bond, double bonds can be described in terms of overlapping atomic orbitals, except that, unlike a single bond (which consists of a single sigma bond), a carbon–carbon double bond consists of one sigma bond and one pi bond. This double bond is stronger than a single covalent bond (611 kJ/mol for C=C vs. 347 kJ/mol for C–C) and also shorter with an average bond length of 1.33 Angstroms (133 pm).

by: With HonorPlease tell me how we did this,
We got ourselves into such a mess again.
We've fought so long we can't remember what the hell it was all about.
I can't count the times I've turned around, cheated my promises, and sold you out.
How is this not a waste of time, these blind eyes won't see me through.
I'm feeling for a hand to hold me now, lift the veil, see the truth.
There's so much further left to climb, and not one inch has been secure.
I'm feeling for a hand to hold me now, lift the veil and endure.
Be it my dexterity for long-winded alibis,
But excuses came full circle months ago.
I've wanted to walk away, but it can't be right,
To forget the knocking and throw the fight,
Silence the wanting and blackout the firelight.
I'm digging deep to find resolve to change, will to draw lines.
I'm putting old ways to the knife, I'm dying here this time.
Because honestly I can't relate,
While lying to your face every day.
With webs of lies spun to justify all of my failures.
I've realized my heart's content,
I may never see an end.
So when you need me I'll be outside throwing rocks at the moon every night
'til the day I die.
