Butane (/ˈbjuːteɪn/) is an organic compound with the formula C4H10 that is an alkane with four carbon atoms. Butane is a gas at room temperature and atmospheric pressure. The term may refer to either of two structural isomers, n-butane or isobutane (or "methylpropane"), or to a mixture of these isomers. In the IUPAC nomenclature, however, "butane" refers only to the n-butane isomer (which is the isomer with the unbranched structure). Butanes are highly flammable, colorless, easily liquefied gases. The name butane comes from the roots but- (from butyric acid) and -ane.
Rotation about the central C−C bond produces two different conformations (trans and gauche) for n-butane.
When oxygen is plentiful, butane burns to form carbon dioxide and water vapor; when oxygen is limited, carbon (soot) or carbon monoxide may also be formed.
When there is sufficient oxygen:
When oxygen is limited:
The maximum adiabatic flame temperature of butane with air is 2,243 K (1,970 °C; 3,578 °F).
I could wait for a long time
Pretend there's hope for this heart of mine
Believe someday I could hear you say
You send me, never go away
But I find myself all alone at night
I got no one, not a soul in sight
See those clouds come a closing in
Now the rain come down here I go
Here I go again, coming 'round the bend
And I'm begging you please
You gotta wait for me
I got it bad for you
I know you feel it too
We oughta see it through
'Cause I got it bad, got it bad for you
Got it bad for you
Another day world turn around
Help me get my feet back on the ground
Funny I'm okay as long as I
Keep keeping you on my mind
Then I see your face and I lose control
I lose myself but I can't let go
Another day I can't bear to face
Lonely man in a lonely place
Time's going to waste
Let's give it a try
On this you can rely
See your face and I lose control
I lose myself and I can't let go
See the clouds come closing in
The rain come down
