Question 1
Ring strain the cause of high molecular reactivity that occurs when the angles in a ring of atoms are not close to "normal"bond angles (90° when the bonds are formed by atoms using pure
p-orbitals, 109.5° using
sp3 hybrid orbitals, 120° using
sp2 orbitals, etc.). The angles in white phosphorus, P
4, measure ________, and P
4 ________ expected to exhibit ring strain and be very reactive.
Question 2
Adenosine triphosphate (ATP) plays an important role in energy transfer within cells. ATP can be considered to be an ester of triphosphoric acid, which is formed by the combination of three phosphoric acid molecules with the elimination of two water molecules. What is the formula of triphosphoric acid?
The activation energy barrier.
