SN1 reaction

The SN1 reaction is a substitution reaction in organic chemistry. "SN" stands for nucleophilic substitution and the "1" represents the fact that the rate-determining step is unimolecular. Thus, the rate equation is often shown as having first-order dependence on electrophile and zero-order dependence on nucleophile. This relationship holds for situations where the amount of nucleophile is much greater than that of the carbocation intermediate. Instead, the rate equation may be more accurately described using steady-state kinetics. The reaction involves a carbocation intermediate and is commonly seen in reactions of secondary or tertiary alkyl halides under strongly basic conditions or, under strongly acidic conditions, with secondary or tertiary alcohols. With primary alkyl halides, the alternative SN2 reaction occurs. In inorganic chemistry, the SN1 reaction is often known as the dissociative mechanism. This dissociation pathway is well-described by the cis effect. A reaction mechanism was first proposed by Christopher Ingold et al. in 1940. This reaction does not depend much on the strength of the nucleophile unlike the SN2 mechanism.

    Inner Light

    by: Zion I

    [Intro]
    And the time says... [x2]
    [Verse 1: Zion I]
    I'm like Golgo 13 assassinator
    Known to those zones microphones and faders
    I slip into
    Where you've never been to
    Come through and witness God within you
    I think you
    Really like what you see
    In your inner most depths the rest is poetry
    And it's spoken
    From the city of Oakland
    Where the flames is hot and rocks be smoking
    No jokin
    We begin to speak
    With the word on the street vibrate to concrete
    As a basis
    Foundations we create this
    Watch for what you wish God will assist
    All endeavors
    Thoughts like feathers
    To carry the bird within your soul to the ethers
    Always and forever
    I still be
    In the place with the grace
    Do you feel me
    We'll be on the run for the new sun
    Til the last day when armaggedeon come
    Armaggedeon come... [x2]
    [Hook:]
    Life is one big road with lots of signs
    (scratching: manifestation)
    If you relax yourself and just chill you can take the time...
    (Relax your mind)
    To be yourself and free your mind...
    (scratching: elevation)
    And when you do it right...
    You know your inner light shines
    Your light shines... [x3]
    (scratching)
    (This ain't no game this is life)
    [Verse 2: Zion I]
    In the middle of the night
    I rhyme right
    While my man Amp whippin up the beat sham
    To inspire we set flames higher
    Callin up the spirit talkin on a live wire
    Just for the conflict
    Just for the place
    Just for the days when I was a mental slave
    Allow my mind to climb when I ride mics
    Take flight jump up withcha satellite
    And get high from the soul less shower
    Creator is the power
    Destruct and devower
    I'm on a Timex and my concepts
    Better represent what I want to come at cha
    Don't got time to play for this worktime
    Everyday I gotta pray for the sunshine
    Take time
    Illuminate self divine
    In a little time realize one mind
    Yo...
    [Hook:]
    Life is one big road with lots of signs
    (scratching: manifestation)
    If you relax yourself and just chill you can take the time...
    (Relax your mind)
    To be yourself and free your mind...
    (scratching: elevation)
    And when you do it right...
    You know your inner light shines
    Your light shines... [x5]
    [Outro:]
    This ain't no game this is... life [x2]
    (scratching)
    This ain't no game this is... [x2]
    (scratching)
    This ain't no game this is... life
    I'm like Golgo 13 assassinator...
    Assassinator... [x2]
    And the time says... [x2]
    In your inner most depths the rest is poetry...
