Answer:
a) BF3
Explanation:
Boron has only 3 valence electrons, so when it bonds with F there will only be 3 electron pairs around the boron atom. Repulsion theory predicts that these three e- pairs should find themselves at the vertices of an equilateral triangle (bond angles of 120 degrees). Thus, BF3 is planar triangular.
