The possible oxidation states of group 13 elements is/are

The possible oxidation states of group 13 elements is/are
  1. +3
  2. \(+1,+3\)
  3. +1
  4. \(+1,+2,+3\)

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).
