Match each of the chemical species in Column I with its property / properties given in corresponding Column II and Column III. No partial marking.<br>Column I - a) $$\text{BeH}_2$$, b) $$\text{CH}_2\text{BrCl}$$, c) $$\text{PF}_6^-$$, d) $$\text{BF}_3$$<br>Column II - 1. $$sp^3d^2$$, 2. $$sp^3$$, 3. $$sp^2$$, 4. $$sp$$<br>Column III - (i) trigonal planar, (ii) octahedral, (iii) distorted tetrahedron, (iv) linear
Correct Answer: 0
PLACEHOLDER ANSWER - the answer is a set of matches. $$\text{BeH}_2$$ has two bond pairs on Be, so it is $$sp$$ and linear (a with 4 and iv). $$\text{CH}_2\text{BrCl}$$ is $$sp^3$$, a tetrahedron distorted by the different atoms (b with 2 and iii). $$\text{PF}_6^-$$ is $$sp^3d^2$$ and octahedral (c with 1 and ii). $$\text{BF}_3$$ is $$sp^2$$ and trigonal planar (d with 3 and i).
