Organic chemistry Flashcards
Carbon
Valance number of 4, will form covalent bonds with H,O,P,S,N
Organic Chemistry
Chemistry in which Carbon is present
I.e. C6H12O6
Non ex. CO2
Monomers
Smaller (single) units,
protein monomers are: amino acids
Nuclei acids monomer : nucleotide
Polymer
3+ smaller units joined together
each microscope has its advantages and disadvantages. which microscope has allowed scientist to conduct systamatic observations and provided them with the closest look into the structure of the cell?
electron microscope
what is an element?
a pure substance containing only one atom
what are isotopes?
a element that differs in the number of nuetrons
what is an ionic bond?
a bond formed when 1+ electrons are transferred
covalent bonding
electrons are shared between atoms
vander waal forces
Intra-Molecular attraction
hydrogen bond
attraction between a hydrogen atom on one H2O molocules and the oxygen
polar
moloclues in which the charges (+,-) are not distributed evenly
cohesion
attraction between molocules of the same substances
surface tension
skin on H2O due to cohesion
adhesion
attraction between molocules of different substances
