20 what is the base-conjugate acid pair when a strong acid is added to methylamine, ch3nh2? base: ch3nh-; conjugate acid: ch3nh2 base: ch3nh3+; conjugate acid: ch3nh2 base: ch3nh2; conjugate acid: ch3nh3+ base: ch3nh2; conjugate acid: ch3nh-

  The base  conjugate   acid pair  when strong acid is added  to  methylamine  CH3NH2   is

base CH3NH2; conjugate  acid: CH3NH3 +

                 Explanation

When   a base CH3CH2   accept   proton  it  form  its  conjugate  acid  which known as methyl  ammonium  ion. Therefore conjugate  acid  of CH3CH2  is CH3NH3+  ion

For   example  when CH3CH2  react with  HCl

CH3CH2  +HCl → CH3CH3+   +   Cl-
