BCH441 - CH 1 EXAM QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS VERIFIED
what property unites C, h, o, n and renders these atoms so appropriate to the
chemistry of life?
ability to form covalent bonds
-covalent bond forming by e- pair sharing
-h likes 1 bond
-c likes 4 bonds
-n likes at least 3 bonds
ovalent bond strength is inversely proportionate to what?
c
-atomic weight of atoms involved
-smaller atom = stronger bond
-H-H>C-H>C-C>C-N
why is carbon so prevalent in biomolecules?
-versatility, 4 bonds per atom
-carbon can form complex organiz molecules
-linear aliphatic structures, cyclic, branched, planar
properties of biomolecules reflect their fitness to the living condition
-macromolecules and their building blocks have a "sense" or directionality
-macromolecules are informational
