Q28 / 160 · AP EAMCET 2020 (21 Sep Shift 2) · Chemistry

The possible oxidation states of group 13 elements is/are

  • A
    +3
  • Correct answer
    B
    \(+1,+3\)
  • C
    +1
  • D
    \(+1,+2,+3\)

Solution

The general oxidation state exhibited by the group 13 elements in the group are +3 and +1 due to its general electronic configuration \(n s^2, n p^1\). As we go down the group of boron family, the tendency to form +1 ion increases. This is due to inert pair effect. Hence, the correct option is (b).

Hence, the correct answer is option: 'B'.
