The type of hybridisation of boron in diborane $(B_2H_6)$ is:

Total number of species from the following with central atom utilising $sp^2$ hybrid orbitals for bonding is.................... $NH_3, SO_2, SiO_2, BeCl_2, C_2H_2, C_2H_4, BCl_3, HCHO, C_6H_6, BF_3, C_2H_4Cl_2$

Explain bond formation in $BCl_{3}$. It is a symmetrical trigonal molecule.

Is there any change in the hybridization of $B$ and $N$ atoms as a result of the following reaction? $BF_3 + NH_3 \to F_3B \cdot NH_3$

What is the state of hybridisation of carbon in $(a)$ $CO_3^{2-}$,$(b)$ diamond,and $(c)$ graphite?

When the hybridisation state of a carbon atom changes from $sp^3$ to $sp^2$ to $sp$,the angle between the hybridised orbitals
