Is there any difference between these propyl molecules?

I have a nomenclature test coming soon and I've learned so many ways of naming things that now I'm confused of which one is the right way, lets say I have this molecule.

...........OH

.............l

....CH3CHCH3

Is there any difference between isopropyl alcohol, isopropanol, sec-propyl alcohol, sec-propanol,

2-alcohol propane, and 2-propanol? ( not sure about the last two)

What are the correct ways to write it?

    ================OH

    ---------------------------------|

    ---------------CH3----------CH--------CH3

    there are two ways of nomenclature

    (I) trivial name or simple name

    (II) I.U.P.A.C. name

    (A) now this compound is -----------ISO PROPYL ALCOHOL;( simple name)

    (B) I.U.PA.C. NAME----------- PROPAN--2-- OL or 2 - PROPANOL

    now your names isopropanol , sec propyl alcohol, sec propanol, & 2 -alcohol propane

    are NOT CORRECT NAMES

    NO DOUBT----------- isoprpyl alcohol is -----secondary alcohol[ as it has --CH--OH )

    [ alcohols are of three types (I) primary alcohol (II) secondary alcohol (III) tertiary alc.]

    p----{ having --CH2OH gp}s----- (having --CH-OH--- gp} t- -{ -having ---C-OH-}

    Isopropyl alcohol, is a common name for isopropanol. A colorless, flammable chemical compound with a strong odor. It has the molecular formula C3H7OH, and is the simplest example of a secondary alcohol, where the alcohol carbon is attached to two(2) other carbons. In organic chemistry, propyl is a three(3) carbon alkyl substituent, with chemical formula -C3H7. It is the substituent form of the alkane propane.

    sec-propanol is true

    here is three c------------->prop

    OH shows an alcohol--------> ol

    OH is on sec c -------------->2

    -----------------------------------------------------

    so : 2- propanol (IUPAC naming)

    the other name of this alcohol is isopropyl alcohol, isopropanol, sec-propyl alcohol,

    2-alcohol propane

    so there is no difference!

    i think it`s better to write sec -->2

    Propan-2-ol is the recommended IUPAC name. Stick to that one.
