To determine the weakest acid from the options given, we need to understand that the acidity of an alcohol is determined by the stability of the conjugate base formed after it donates a proton (H+). The more stable the conjugate base, the stronger the acid.

1. 2-methyl-2-propanol: This forms a tertiary carbocation, which is highly stable due to hyperconjugation and inductive effect.

2. 1-butanol: This forms a primary carbocation, which is less stable than a tertiary carbocation.

3. 2-butanol: This forms a secondary carbocation, which is more stable than a primary carbocation but less stable than a tertiary carbocation.

Therefore, the weakest acid among the given options is 1-butanol because it forms the least stable conjugate base.
