You can see that the bond energy of a double bond is greater than that of a
single bond, though not twice as great. This suggests that the two bonds in C=C
may not be identical. In fact, two kinds of covalent bond are involved. (a) A bond ...

Stereochemistry of Organic Compounds: Principles and ...
It has previously been noted that rotation about a single bond (e.g., C — C) is
relatively free while rotation around a double bond (e.g., C = C) is highly
restricted. Between these two extremes, there exist also intermediate bonds with
fractional ...

Chemistry of Arsenic, Antimony and Bismuth
This trend is observed for the elements phosphorus to bismuth, but the well-
known weakness of the N-N single bond is immediately apparent, this bond
being significantly weaker than the P-P single bond. The origin of this apparent
anomaly ...

Introduction to Phosphorous Chemistry
However, in tertiary amine oxides, the bond energy term for the N— 0 bond is
usually given as 210-90 kJ mol"1 (50-70 kcal mol"1), whereas the term for an N0
single bond in, for example, hydroxylamine derivatives R2N— 0R', is about 150-
90 ...

8.6, unweakened single bond energies were estimated. For oxygen this value, £'"
, 434 kJ mol ~ ', is about three times the value of the oxygen-oxygen single bond
energy determined experimentally from the dissociation of H2O2, 142 kJ mol~1.

General Chemistry, Enhanced Edition
Although a double bond is stronger than a single bond, it is not necessarily less
reactive. Ethylene, CH2PCH2, for example, is more reactive than ethane, CH3
OCH3, where carbon atoms are linked through a single bond. The reactivity of ...

Pi bond energies are calculated as double-bond energies minus single-bond
energies for the same element, or (triple-bond energies minus single-bond
energies) times one-half. c Schmidt et al. give a value for the pi bond energy of
the N-N ...

Undergraduate Instrumental Analysis, Sixth Edition
The term f varies with bond strength; a simple but useful approximation is that a
triple bond between two atoms is 3Â as strong as a single bond between the
same two atoms, so f would be 3Â as large for the triple bond. A double bond is
twice ...
