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 .

Options

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

A

Explanation

`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.
