PSU Chem 110B Final Exam Questions
With 100% Correct Answers 2025/2026
Updated Test.
standard states of elements - Answer All metals and metalloids are solids at standard state
except for mercury, which is a liquid. Noble gases (group 8) are all monatomic gases. Several
elements exist as diatomic species at standard state, these include group 7 (F2, Cl2, Br2, and I2)
plus hydrogen (H2), nitrogen (N2), and oxygen (O2). All of these diatomic species are gases at
standard state except for Br2 (liquid) and I2 (solid). All other nonmetals are solids.
Carbon----> graphite
5 prime - Answer n terminus
3 prime - Answer c terminus
Alkane - Answer hydrocarbons with all single bonds
All have tetrahedral geometry
Alkenes - Answer Hydrocarbons with one or more carbon-carbon double bonds
Alkynes - Answer hydrocarbons with one or more triple bonds between carbon atoms
Aromatic - Answer alternating double/single bonds in a ring
geometric isomers - Answer Compounds that have the same molecular formula but differ in
the spatial arrangements of their atoms.
constitutional isomers - Answer compounds with the same molecular formula but different
connections among their atoms
2 connected atoms NO lone pairs - Answer Linear
180 degrees
