Answer 1

2- A suppose any atom x, which have forcer é but none is lone pair ie to that mean a é can make four bonds suppose bonded groelps is y ire sp-linear yoxoy sp2- planar sp3 - Tetrahedral the hybridisation of a will be sp3. when hybridi- sation is sp3 with none lone pair geometry becomes Tetrahedsants. option (1) correct
