Q)
(chatquestion)...Consider the following statements for transition elements
(1) Transition elements show variable oxidation states because energy difference between (n-1)d subshell and ns
subshell is small
(2) All the transition elements exhibit a minimum oxidation state of (+2) except in case of Cr, Cu, Ag, Au and Hg
which have a minimum oxidation state of (+1)
(3) (+2) oxidation state becomes more stable from left to right in 3d series
(4) V2* and Cr2 salts are very weak reducing agents?
Ofthese, the correct statements are
(a) 1, 2 and 3
16.
(b) 2, 3 and 4
(c) 1, 2 and 4
(d) 1, 3 and 4
