没错啊，所以你从来没见过连在C上的H会形成氢键吧？因为H带的正电荷太少。
What is an ionic bond and a covalent bond?Answer and Explanation: An ionic bond is a bond formed whenonly one of its atoms or moieties transfer theelectrons, while covalent bond is formed when both atoms (or moeieties) shared their valence electrons to form the bond. An example of ionic...
A molecule is considered polar if it has an overall dipole moment. The dipole moment of the compound depends if the compound has polar bonds and if the geometry of the compound will permit a net dipole moment. Bond dipole moments occur due to differences in electronegativity....
Polar vs. Nonpolar Covalent Bonds: Examples | What are Polar & Nonpolar Covalent Bonds? from Chapter 1 / Lesson 5 2M Learn about polar vs. nonpolar covalent bonds. Discover polar and nonpolar covalent bond examples, and examine how to predict polar vs. nonpolar bonds. Related to this Ques...
A chemical bond is a lasting attraction between two or more atoms that allows for the formation of chemical compounds. An example is covalent bonding, where valence electrons are shared between two or more atoms. Electronegativity is the tendency of an atom in such a bond ...
The electron pairs that participate in acovalent bondare called bonding pairs or shared pairs. Typically,sharing bonding pairsallows each atom to achieve a stable outer electron shell, similar to that seen in noble gas atoms. Polar and Nonpolar Covalent Bonds ...
Tyrosine has a side chain, which is, in fact, a benzene ring with a hydroxyl -OH group attached. This scheme gives it a final structure of CH2-C6H4 OH where the benzene ring is hydrophobic and contributes to tyrosine’s nonpolar, water-repellent behavior in aqueous solutions. However, yo...
Cyclohexane - Cyclohexane is a cycloalkane with the molecular formula C6H12. Cyclohexane is nonpolar. Cyclohexane is a colourless, flammable liquid with a distinctive detergent-like odour, reminiscent of cleaning products.
Depending on the configuration of the Ser364 side chain, the Ser364 hydroxyl group may function as a hydrogen-bond acceptor bonded to the Ser364 nitrogen at the 1 position (as shown in Fig. 3b), or as another hydrogen-bond donor to the ketone oxygen atom at the 2 position. A ...
Is the H-H bond in hydrogen gas ionic, polar covalent, or nonpolar covalent? Explain. If a hydrogen bond is weaker than a covalent bond, it is necessary to have 5 kcal/mol to break a hydrogen bond and 100 kcal/mol to break a covalent bond. Why do t...
