However, some flavoproteins contain a flavin that is tethered to two amino acids. In the last decade, many studies have focused on elucidating the mechanism(s) of covalent flavin incorporation (flavinylation) and the possible role(s) of covalent protein–flavi...
While single, double, and triple bonds are the basis for organic chemistry, a quadruple covalent bond was an unusual discovery by F. Albert Cotton and C.B. Harris in the molecule potassium octachlorodirhenate.Answer and Explanation: A covalent bond is an intramolecular force between two atoms...
What is a covalent bond and ionic bond?Chemical Bonding:There are different types of chemical bonding in nature. The two main categories of bonding are ionic and covalent which lead to very different types of chemical compounds.Answer and Explanation: ...
A coordinate covalent bond is a pair of electrons shared between two atoms which originated on one of the atoms;a covalent bond is a shared pair of electrons. Once formed, there is no difference between them. In an ammonium ion there are four covalent bonds,one of which is a coordinate ...
F2. This is typically described in high-school chemistry as a simple example of covalent electron-sharing, but the purely covalent contribution to the bond turns out to be repulsive. The atoms can instead be considered to be held together by resonant mixing between ionic and covalent forms, as...
What type of fission of a covalent bond produce free radicals? Give an example with proper sign. View Solution Reagents which attack organic compounds may be classified as electrophiles, nucleophiles and free radicals. Name the type of the fission of a covalent bond which gives free radicals. ...
What is the difference between an ionic bond and a covalent bond?相关知识点: 试题来源: 解析 An ionic bond is formed when electrons are transferred from one aton to another to form negative and positive ions.A colvalent bond is formed when electrons are shared between two atoms....
How can you tell if a covalent bond is polar or nonpolar? Covalent bonds that are polar have an unequal sharing of a pair of electrons. This would be determined by an electronegativity difference of the two elements falling between 0.4 and 1.7. Non-polar bonds have less than 0.4 electronegat...
Here is the definition of a covalent compound as used in chemistry, chemical engineering, and physics, plus several examples of covalent compounds.
