Chapter 2, Problem 47P

Which of the following bases are strong enough to deprotonate ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{CH}}_{\text{2}}\text{C}\equiv \text{CH}\left(\text{p}{K}_{\text{a}}=25\right)$, so that equilibrium favors the products: (a) ${\text{H}}_{\text{2}}\text{O}$; (b) $\text{NaOH}$; (c) ${\text{NaNH}}_{\text{2}}$; (d) ${\text{NH}}_3$; (e) $\text{NaH}$; (f) ${\text{CH}}_{\text{3}}\text{Li}$?
