    pKa is a value which is related to the acid dissociation constant Ka

    pKa = - log Ka

    i. e. Ka = 10^-pKa

    The deprotonation reaction of acetylene is:

    HC≡CH ↔ HC≡C⁻ + H⁺

    pKa (HC≡CH) = 25

    Solvents with pKa greater than 25 will deprotonate acetylene.

    Ans: CH2=CH⁻ pka = 44 and CH3NH⁻ pka = 40
