Explanation / Answer

1st 2 are not visible

23)

CBr4 is tetrahedral as C has 4 valence electrons and it forms 4 bonds

So, it is sp3 hybridised and hence tetrahedral

Answer: A

24)

number of valence electrons in B = 3

All 3 are used in forming bonds

So, B is sp2 hybridised and it is trigonal planar

Due to symmetry, there is no dipole moment and hence it is non polar

Answer: D
