Select the appropriate statements and arrange them in a logical order to explain the bonding in BeF2. i. Each of the singly occupied hybrid orbitals on Be overlaps with a singly occupied 2p orbital on an F atom. ii. The unhybridized 2p orbitals on Be interact with the 2p orbitals on the F atoms to form pi bonds. iii. The 2s and one of the 2p orbitals on Be combine to form two sp hybrid orbitals. iv. A 2s electron is promoted to a 2p orbital on Be. v. The 2s electrons in Be are promoted to 2p orbitals. vi. Each of the singly occupied 2p orbitals on Be overlaps with a singly occupied 2s orbital on a F atom. a.v, vi, ii b. v,vi c. iii, i, ii d. iv, iii, i e. iv, iii, i, ii
