in an IR explanation in cyclohexanol there are CH2 groups in the ring and that in the IR spectrum was at about v= 1454cm-1 so how will I say that will I say a sharrp, strond band at v=1454cm-1 which illustrates v(C-H) bend of the CH2 groups of cyclohexanol or a strong band at v=1454cm-111 which illustrates v(CH2) of cyclohexanol????

My experience is that the C-H bending at 1454 cm^-1 is not all that strong nor all that sharp; however, these are personal calls and it varies, I suppose, with both the amount of sample and the operator so you call it like it is. I would say ......v = 1454 cm^-1 due to C-H bending of the CH2 groups of cyclohexanol.
By the way, is you used caps for the beginning of a sentence and periods or ?? for the end of a sentence it certainly would improve the readability of your question.
