Which reactions involves a change in the electron `-` pair geometry `( i.e.,` hybridisation ) for the under lined geometry ?

Options

A. `underset(bar)(B)F_(3)+F^(-)rarr underset(bar)(B)F_(4)^(-)`
B. `underset(bar)(N)H_(3)+H^(+)rarr underset(bar)(N)H_(4)^(+)`
C. `2underset(bar)(S)O_(2)+O_(2)rarr2underset(bar)(S)O_(3)`
D. `H_(2)underset(bar)(O)+H^(+)rarrH_(3)underset(bar)(O)^(+)`

Answer

A

Explanation

`BF_(3)(sp^(2))+F^(-)rarrBF_(4)^(-)(sp^(3))`
