Given here are 1H-NMR and 13C-NMR spectral data for two compounds. Each showsstrong, sharp absorption between 1700 and 1720 cm1 and strong, broad absorptionover the region 25003000 cm1. Propose a structural formula for each compound.
CHEM 111 - CSU Week 01 Notes StudySoup - Avery 1.1: States of Matter • Matter: anything that has mass and occupies space • Mass: the property that defines the quantity of matter in an object • Chemistry: the study of the composition, structure, and properties of matter and of the energy consumed or given off when matter undergoes a change • Solid: a form of matter that has a definite shape and volume • Liquid: a form of matter that has a definite volume but takes the shape of its container • Gas: a form of matter that has neither definite volume nor shape, and that expands to fill it’s container • Atom: the smallest particle of an element that retains the chemical characteristics of the element • Molecule: a collection of atoms chemically bonded together • Chemical Bond: a force that holds two atoms in a molecule or a compound together • Sublimation: transformation of a solid directly into a gas • Deposition: transformation of a gas directly into a solid • Three states of water: • Ice: particles are held together in a rigid, three-dimensional crystalline pattern • Water: particles are close together but are free to tumble over one another • Vapor: particles are far apart, largely independent of one another, and able to move freely • Ice—>Melting—>Water—>Vaporizaton—>Vapor • Vapor—>Consensation—>Water—>Freezing—>Ice 1.3: Classes of Matter • Pure Substance: matter that cannot be separated into simpler matte
