Solution: A Bronsted-Lowry Base is defined as a solution that accept proton/s. hydroxide ion, OH^{-} is a Bronted-Lowry base because it have one negative charge and it can accept 1 proton in the form of H^{+} ion.
Lewis base is defined as an electron rich species that can donate its electron pair to electron deficient species. Here, due to negative charge, hydroxide ion is electron rich and can attack on electron deficient carbon atom or carbocation.
The organic product formed by the reaction of hydroxide ion OH^{-} and carbocation CH_{3}^{+} will be as follows:
OH^{-}+CH_{3}^{+}\rightarrow CH_{3}OH
Thus, the organic product formed will be alcohol.
