NEET Chemistry (general) Match the Following Question
Type: Match the Following-match the column-Hard-Class 12
Match Column-I with Column-II.
Column-I Column-II (a) Chromate ion (i) Tetrahedral (b) Dichromate ion (ii) 126° bond angle (c) Oxidation state of chromium in chromate (iii) +6 (d) Oxidation state of chromium in dichromate (iv) +6
Choose the correct matching:
A
a-i, b-ii, c-iii, d-iv
B
a-ii, b-i, c-iv, d-iii
C
a-iii, b-iv, c-i, d-ii
D
a-i, b-iii, c-ii, d-iv
Correct Answer
Option A
Detailed Explanation
The chromate ion (CrO4^2-) is tetrahedral in structure, while the dichromate ion (Cr2O7^2-) has a bond angle of 126° due to its structure consisting of two tetrahedra. The oxidation states of chromium in both chromate and dichromate are +6.
