NEET levelSingle correct optionDifficulty 1 of 3pb169

The shape of $BF X_{3}$ and the hybridisation of boron in it are

Alinear, $s p$
Btetrahedral, $s p^{3}$
Cpyramidal, $s p^{3}$
Dtrigonal planar, $s p^{2}$

Answer: D

Boron has three bond pairs and no lone pair, so it is

s p^{2}

hybridised and the molecule is trigonal planar with

12 0^{\circ}

angles.
