Which of the following conversions involves change in both hybridisation and shape ?

Answer»

`CH_(4)toC_(2)H_(6)`
`NH_(3)toNH_(4)^(+)`
`BF_(3)toBF_(4)^(-)`
`H_(2)OtoH_(3)O^(+)`

Solution :`{:("Compound","Hybridization","SHAPE"),(CH_(4),sp^(3),"Tetrahedral"),(C_(2)H_(6),sp^(3),"Tetrahedral"),(NH_(3),sp^(3),"Trigonal pyramidal"),(NH_(4)^(+),sp^(3),"Tetrahedral"),(BF_(3),sp^(2),"Trigonal planar"),(BF_(4)^(-),sp^(3),"Tetrahedral"),(H_(2)O,sp^(3),"Angular shaped"),(H_(3)O^(+),sp^(3),"Tetrahedral"):}`
Only option (C ) satisfies the GIVEN CONDITIONS.
