Vedclass · Accepted Answer

$B_2H_6$ is not an electron-deficient molecule.

Vedclass · Answer

(A) $1$. $B_2H_6$ (diborane) is a classic example of an electron-deficient molecule because it has only $12$ valence electrons,which are insufficient to form the required number of covalent bonds for its structure,leading to $3c-2e$ (three-center two-electron) bonds. Thus,statement $A$ is incorrect.$2$. $BF_3$ has a trigonal planar geometry,and due to its symmetry,the individual $B-F$ bond dipoles cancel each other out,resulting in a net dipole moment of zero. Statement $B$ is correct.$3$. Hydroboration-oxidation is a stereospecific syn-addition reaction that follows anti-Markovnikov's rule to produce alcohols. Statement $C$ is correct.$4$. $BF_3$ is trigonal planar ($sp^2$ hybridization),whereas $BrF_3$ is $T$-shaped ($sp^3d$ hybridization with two lone pairs on $Br$). Their shapes are indeed different. Statement $D$ is correct.
