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...
How is sodium sulphide formed when sodium reacts with sulphur. 01:06 What is a covalent bond ? How many covalent bonds are present in the f... 04:58 Distinguish between a double bond and a triple bond. Give one example ... 02:01Exams...
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 an example of a nonpolar covalent bond? An example of a non-polar covalent bond would be carbon dioxide. The bond between two non-metals that have a relatively low electronegativity difference between the two elements leads to a non-polar covalent interaction. What is an example of ...
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 is a pi bond ? Explain with example. 04:03 Give one example of each molecule with SP^2 and SP^3 hybrid bond. 03:31 Explain why H2O is polar molecule but CO2 is not ? 03:59 Among the compounds, NH3, HF and CH4 in which the hydrogen bonding is ... 02:10 Which of the ...
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....
Ionic Bond - Electrons can be transferred from one atom to another. For example, Sodium (Na) atom transfers one electron to Chlorine (Cl) atom to form an Ionic Bond for Salt (NaCl) molecule. Covalent Bond - Two atoms share pairs of outermost electrons with each other. For example, 2 ...
