The hydroboration oxidation of an alkene will give the alcohol as the product and the OH group will attach to the carbon which is less hindered. Thus this reaction follows Anti-Markownikoff's rule.
Hence isobutylene on hydroboration oxidation will isobutyl alcohol.

Isobutylene on hydroboration followed by oxidation with hydrogen perox...
Explanation:
Hydroboration-oxidation is a two-step reaction used to convert alkenes into alcohols. In the hydroboration step, the alkene reacts with borane (BH3) to form an organoborane compound. In the oxidation step, the organoborane is treated with hydrogen peroxide (H2O2) in the presence of base to yield an alcohol.
Hydroboration of isobutylene:
Isobutylene is an alkene with the molecular formula C4H8. In the hydroboration step, isobutylene reacts with borane to form an organoborane compound.
Oxidation of the organoborane:
In the oxidation step, the organoborane compound is treated with hydrogen peroxide (H2O2) in the presence of base. The base is usually sodium hydroxide (NaOH) or potassium hydroxide (KOH).
Conversion to tert-butyl alcohol:
The hydroboration-oxidation of isobutylene yields tert-butyl alcohol (also known as 2-methyl-2-propanol). The reaction proceeds as follows:
1. Hydroboration:
Isobutylene reacts with borane (BH3) to form an organoborane compound, which can be represented as R3B.
2. Oxidation:
The organoborane compound is then treated with hydrogen peroxide (H2O2) in the presence of base (NaOH or KOH). This results in the oxidation of the boron atom and the formation of an alcohol.
In the case of isobutylene, the hydroboration-oxidation reaction yields tert-butyl alcohol. The structure of tert-butyl alcohol is (CH3)3COH, where the hydroxyl group is attached to a tertiary carbon atom.
Therefore, the correct answer is option D: tert-butyl alcohol.
