Chem 115 Exam 3 2025/2026 Exam
Questions and Correct Answers | New
Update
covalent bond - 🧠 ANSWER ✔✔can be formed when the orbitals of two
atoms overlap and are filled with pairs of electrons
greater orbital overlap - 🧠 ANSWER ✔✔stronger and more stable bond
linear - 🧠 ANSWER ✔✔two electron groups (linear) 180 degrees
trigonal planar - 🧠 ANSWER ✔✔three electron groups (trigonal planar or
bent) 120 degrees
tetrahedral - 🧠 ANSWER ✔✔four electron groups (tetrahedral, trigonal
pyramidal, or bent) 109.5 degrees
trigonal bipyramidal - 🧠 ANSWER ✔✔five electron groups (trigonal
bipyramidal, seesaw, t-shaped, or linear)
octahedral - 🧠 ANSWER ✔✔six electron groups (octahedral, square
pyramidal, square planar)

, double bonds - 🧠 ANSWER ✔✔require one p orbital from each atom
triple bonds - 🧠 ANSWER ✔✔require two p orbitals from each atom
hybridization - 🧠 ANSWER ✔✔can be determined directly from VSEPR
theory (number of electron groups)
two electron groups - 🧠 ANSWER ✔✔sp hybridization
three electron groups - 🧠 ANSWER ✔✔sp2 hybridization
four electron groups - 🧠 ANSWER ✔✔sp3 hybridization
hybrid orbitals - 🧠 ANSWER ✔✔form when atomic orbitals in the valence
shell of a central atom combine, determined by the number of electrons in
the valence shell
multiple bonds - 🧠 ANSWER ✔✔use electrons in p orbitals to form pi bonds
which reduces the hybridization of the sigma bond
alkanes - 🧠 ANSWER ✔✔a hydrocarbon containing only single covalent
bonds
gas - 🧠 ANSWER ✔✔1-4 carbons
liquid - 🧠 ANSWER ✔✔5-12 carbons
