Identify which one is expected to undergo elimination more rapidly when treated with a strong base. The bond-line structure of the compound has a SMILES string of [2H]C([2H])([2H])C(C([2H])([2H])[2H ])(C([2H])([2H])[2H])Br. The bond-line structure of the compound has a SMILES string of CC(C)(C)Br.

answer; i believe that the correct answer is (a) potassium(k)

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-

its first and third is your answer i did the qustion the fourth isnt right
