Q. $B{F}_3$ is planar and electron deficient compound. Hybridisation and number of electrons around the central atom, respectively are:

Q. The hybridization of the central atoms of compounds $A,B,C$ and $D$ are $s{p}^{3}d,s{p}^3,s{p}^2$ and $sp$ respectively. If the compounds $A$ and $D$ have the same shape like $I_3^{-}$ and the compounds $B$ and $C$ have the same shape like water molecule, then the value of $P+Q+R+S$ is:(Given that $P,Q,R$ and $S$ are the number of lone pairs of electrons on central atoms of compounds $A,B,C$ and $D$ respectively.)

Q. The geometry and the type of hybrid orbital present about the central atom in $B{F}_3$ are trigonal planar and $s{p}^2$. If true enter 1, else enter 0.
