For the Daniell cell ` Zn| Zn^(2+) || Cu^(2+) | Cu` with The questions consist of two statements each, printed as Assertion and Reason. While answering these questions you are required to choose any one of the following four responses : Alpha (alpha)- amino acids exist an internal salt in solution as they have amino and carboxylic acid groupa in near vicinity. ` H+` ion given by carboxylic group `(-COOH)` is captured by amino group `(-NH_2)` having lone pair of electrons .A. If both assertion and reason are terue and the reason is the correct explanation of the assertion .B. If both assertion ans reason are true but reason is not the correct explanation of the assertion .C. If assertion is true but reason is false .D. If assertion is false but reason is true. |

Answer» Correct Answer - A `NH_(2)-CH_(2)-COOH` is a typical alpha-amino acid. In solution it exists as m intemal slt or Zwitter ion, `(^(+)HH_(3)-CH_(3)-COO^(-))` because the proton `(H^(+))` of `COOH` group is captured by `-NH_(2)` has a lone pair of electrons on N atom. |
