Question

Which one of the following is correct order of given isotopes? I. T 2 > D 2 > P 2 (order of boiling point) II. T 2 > D 2 > P 2 (order of bond energy) III. T 2 = D 2 = P 2 (order of bond length) IV. T 2 < D 2 < P 2 (order of reactivity with Cl 2 )

TestHub · Accepted Answer

Protium ( P ) , deuterium ( D ) and tritium ( T ) are the three isotopes of hydrogen. These isotopes follow the order in different contexts as shown below : T 2 > D 2 > P 2 [Order of boiling point (BP)] T 2 > D 2 > P 2 [Order of bond energy ( BE ) ] T 2 = D 2 = P 2 [Order of bond length ( BL ) ] T 2 < D 2 < P 2 [Order of reactivity with Cl 2 ] Hence, all the given order are correct.
