Bond lengths range from 147.9 pm for simple amines to 147.5 pm for C-N= compounds such as nitromethane to 135.2 pm for partial double bonds in pyridine to 115.8 pm for triple bonds as in nitriles. [2] A CN bond is strongly polarized towards nitrogen (the electronegativities of C and N are 2.55 and 3.04, respectively) and subsequently molecular ...
The term "affiliate" is broadly defined and includes parent companies, companies that share a parent company with the bank, companies that are under other types of common control with the bank (e.g. by a trust), companies with interlocking directors (a majority of directors, trustees, etc. are the same as a majority of the bank's), subsidiaries ...
A bond purchased on or after January 1, 1990, is tax-free (subject to income limitations) if used to pay tuition and fees at an eligible institution. In 2002, the Treasury Department started changing the savings bond program by lowering interest rates and closing its marketing offices. [2]
A chemical bond is the association of atoms or ions to form molecules, crystals, and other structures. The bond may result from the electrostatic force between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds, or some combination of these effects.
In finance, a bond is a type of security under which the issuer owes the holder a debt, and is obliged – depending on the terms – to provide cash flow to the creditor (e.g. repay the principal (i.e. amount borrowed) of the bond at the maturity date and interest (called the coupon) over a specified amount of time. [1])
The three sp 2 orbitals lie in a plane with ~120° angles. The p-orbital is perpendicular to this plane. When the carbon atoms approach each other, two of the sp 2 orbitals overlap to form a sigma bond. At the same time, the two p-orbitals approach (again in the same plane) and together they form a pi bond. For maximum overlap, the p-orbitals ...
Moreover, the multiple bonds of the elements with n=2 are much stronger than usual, because lone pair repulsion weakens their sigma bonding but not their pi bonding. [2] An example is the rapid polymerization that occurs upon condensation of disulfur , the heavy analogue of O 2 .
The form of these bonds was both lottery and annuity. The Bank of England and government bonds were introduced in England by William III of England (also called William of Orange), who financed England's war efforts by copying the approach of issuing bonds and raising government debt from the Seven Dutch Provinces, where he ruled as a stadtholder.
