Oxidation of alkenes by cleavage with the acidic or alkaline `KmNO_(4)` of acidic `K_(2)Cr_(2)O_(7)` at higher temperature yields products depending upon the nature of alkene. A hot solultion of `KMnO_(4)` is a strong oxidising agent which gives only ketones and carboxylic acids and not aldehydes (as they cannot be isolated). Oxidation of alkenes with `OsO_(4)` followed by alcoholic `NaHSO_(3)` or `Na_(2)SO_(3)` yeilds glycols. Answer the following questions: Which of these compounds on oxidation with hot `KMnO_(4)` gives only butanoic acid?A. Oct-3-eneB. Oct-4-eneC. Oct-2-eneD. 3-Methylhep-3-ene
