Question

a molecule containing a central atom with sp hybridization has a(n) __________ electron geometry. square planar bent octahedral trigonal pyramidal linear

Explanation:

When a central atom has sp hybridization, it forms two sp hybrid orbitals. These two orbitals are oriented at 180 degrees to each other. Electron - geometry describes the arrangement of electron - groups (bonding and non - bonding) around the central atom. For sp hybridization, there are two electron - groups (since sp hybridization results from the combination of one s and one p orbital, and in the absence of lone pairs, these two orbitals are used for bonding). The arrangement of two electron - groups around a central atom is linear.

• Square planar geometry is associated with \(d^{2}sp^{3}\) or \(sp^{3}d^{2}\) hybridization (6 electron - groups in an octahedral arrangement with 2 lone pairs in opposite positions).
• Bent geometry can be due to \(sp^{2}\) (e.g., \(SO_{2}\) with a lone pair) or \(sp^{3}\) (e.g., \(H_{2}O\) with two lone pairs) hybridization.
• Octahedral geometry is for \(sp^{3}d^{2}\) or \(d^{2}sp^{3}\) hybridization (6 electron - groups).
• Trigonal pyramidal geometry is for \(sp^{3}\) hybridization with one lone pair (4 electron - groups in a tetrahedral arrangement, but one is a lone pair).

Answer:

linear
