QUESTIONS AND ANSWERS LATEST
EDITION
What |do |Biochemists |study? |- |ANS |-1. |The |relationship |between |structure |and |function |of |
biomolecules
2. |Chemical |reactions |of |organisms
3. |Communication |within |and |among |organisms
Smaller |elements |are |favored |because |they |can |form |stable |covalent |bonds. |T |or |F |- |ANS |-
True. |Strong |bonds |form |by |significant |overlap |of |atoms, |such |as |carbon |and |hydrogen, |
allowing |them |to |share |electrons.
What |is |the |bond |angle |of |a |Linear |molecule? |- |ANS |-180 |degrees
What |is |the |bond |angle |of |a |Trigonal |Planar? |- |ANS |-120 |degrees
What |is |the |bond |angle |of |a |Trigonal |Pyramidal? |- |ANS |-107.5 |degrees
what |is |the |bond |angle |of |Tetrahedral? |- |ANS |-109.5 |degrees
What |is |carbon |referred |to |in |the |chemical |world? |- |ANS |-The |superglue
What |does |organic |chemistry |study? |- |ANS |-Focuses |on |the |chemical |and |physical |properties |
of |carbon |compounds
, What |does |inorganic |chemistry |study? |- |ANS |-The |field |dealing |with |metals, |minerals, |and |
other |non-organic |compounds
How |many |bonds |can |a |Carbon |form? |- |ANS |-4! |Due |to |having |4 |valence |electrons
What |is |a |long |chain |of |carbons |called? |- |ANS |-Polymers
What |is |a |cyclic |compound? |- |ANS |-Carbons |joined |together |in |a |closed |chain
What |are |carbon |compounds |called? |- |ANS |-Alkanes
Condensed |structures |give |a |better |idea |of |a |molecules |structure, |compared |to |chemical |
formula. |T |or |F |- |ANS |-T
Structural |formula |gives |an |even |better |idea |of |a |molecules |structure, |compared |to |chemical |
formula |- |ANS |-T
Advantage |of |cyclic |carbon |compounds |- |ANS |-They |are |more |restricted |in |their |movements |
and |orientation |- |advantageous |for |building |structures |and |maintaining |shape
Carbon |can |form |double |and |triple |bonds |with |other |carbon |atoms |or |atoms |of |other |
elements. |T |or |F |- |ANS |-T
Line-bond |Drawing |- |ANS |-Most |efficient |method |to |show |structure, |but |requires |the |most |
interpretation.
