How to find in a covalent bond that which atom is more electronegative?? |
| Answer» The electrons in a covalent bond between two different atoms (H and Cl in this case) are not equally shared by the atoms. This is due to the electronegativity difference between the two atoms. The more electronegative atom (Cl) has greater share of the electrons than the less electronegative atom (H). | |

What are bond parameters...?? |
| Answer» In molecular geometry, bond length or bond distance is defined as the average distance between nuclei of two bonded atoms in a molecule. It is a transferable property of a bond between atoms of fixed types, relatively independent of the rest of the molecule.\xa0Bond parameters\xa0refer to the characterization of covalent\xa0bond\xa0on the basis of various\xa0parameters\xa0like\xa0bond length,\xa0bond angle,\xa0bond\xa0enthalpy.\xa0Bond length\xa0is defined as the equilibrium distance between the nuclei of two bonded atoms in a molecule.\xa0Bond lengths\xa0are measured by spectroscopic X-ray diffraction and electron-diffraction techniques. In the case of a covalent\xa0bond, the contribution from each atom is called the covalent radius of that atom. | |

| Answer» | |
| 2896. |
What do you mean by limiting reagent . Give one example. |
| Answer» The agent which is completely consumed during chemical reaction.<br>The reactant that is entirely used up in a reaction is called as limiting reagent.3H2\xa0+ N2\xa0→ 2NH3In the reaction given above, 3 moles of Hydrogen gas are required to react with 1 mole of\xa0nitrogen gas\xa0to form 2 moles of ammonia. But what if, during the reaction, only 2 moles of hydrogen gas are available along with 1 mole of nitrogen.In that case, the entire quantity of nitrogen cannot be used (because the entirety of nitrogen requires 3 moles of hydrogen gas to react). Hence, the hydrogen gas is limiting the reaction and is therefore called the limiting reagent for this reaction. | |
| 2897. |
Among the molecules No+, N2 and No2 identifiy the species which is isoelectronic with Co |
| Answer» CO is isoelectronic with NO+ and N2. CO has 14 electrons, 8 from oxygen and 6 from carbon. NO has 15 electrons 8 from oxygen and 7 from nitogen. But, as it becomes NO+, it loses an electron and the number of electrons is 14. Similarly, N2 has 14 electrons, 7 from each of the nitrogen atoms. | |
| 2898. |
What is chemical.....?? |
| Answer» A chemical substance is a form of matter having constant chemical composition and characteristic properties. Some references add that chemical substance cannot be separated into its constituent elements by physical separation methods, i.e., without breaking chemical bonds. | |
