organic chemistry I

  • Chemical structure diagram of an amino acid with labeled sp3 hybridization sites.

    Hybridization

  • A detailed step-by-step organic chemistry reaction mechanism illustrating the bromination of cyclopentene where a hydrogen is replaced by a bromine atom, including ring expansion and reformation, with each step labeled and annotated.

    Mechanisms

  • Educational diagram explaining carbon and non-carbon substitutes at C=1. It shows structure of a chain with numbered carbons, and two molecules, one with a cyclopentyl ring and another with an alcohol group, with text describing the concepts.

    naming rules

  • A chemistry diagram illustrating Williamson Ether Formation, showing chemical reactions with molecules, arrows, and handwritten notes in black, pink, and gray, describing the process steps and routes.

    Synthesis

  • Reactions

  • Diagram comparing two amino acids, with their chiral centers, and explaining the mirror images and stereochemistry, including the same substituents on both stereocenters and the concept of enantiomers.

    Fischer projections

  • Diagram showing structural representations of a molecule with hydrogen atoms, a 3D crystal lattice with up and down arrows indicating spin directions, and a 2D network with numbered edges illustrating possible atomic exchanges.

    Chair conformation

  • Stereochemistry

  • Line graph displaying transmittance percentage vs. wavenumber, annotated with peaks indicating alkyne to C-H at 3300 cm^-1 and alkene just below 2200 cm^-1, with chemical structures of 1-propanol, dipropyl ether, 1-pentyne, and methyl phenyl ether below the graph.

    IR

  • Diagram of a benzene ring with numbered signals 0 to 4, showing methyl groups, a methyl decorated carbon, and annotations about hydrogen counting, symmetry, and variable distances from substituents.

    NMR Signals

  • Hand-drawn chemical structure of 2-(4-bromopentyl)-6-methylphenol with numbered carbons, hydroxyl group, methyl group, and bromine substituent, annotated with notes explaining phenol group priority, alphabetical atom order, and carbon-2 definition, with colorful text and labels.

    IUPAC naming

  • Educational illustration explaining how to account for 24 carbons in a molecule, showing a molecule with two non-equivalent hydrogens, a benzene ring with methyl group, and the importance of two signals in NMR spectra. Includes a note that hydrogens won't work and a suggested solution with a detailed molecular structure maintaining two signals.

    NMR Interpretation

  • Structural diagram of a molecule with a central circle and attached groups: two methyl groups, two hydroxyl groups, and two hydrogen atoms.
