What is hyperconjugation in easy way?? |
| Answer» A general stabilizing interaction which involves the delocalization of sigma electrons of a C-H bond of an alkyl group directly attached to an unsaturated system (or) to a species with an unshared p -orbital such as Carbocations (or) free radicals is known as hyperconjugation. Hyperconjugation is a permanent effect. Ex: Hyperconjugation in ethyl carbo cation. One of the carbon-hydrogen bonds of the methyl group aligns in the same plane with the empty p -orbital of the positively charged carbon atom.<br>In simple words the movement of sigma bond is called hyperconjugation....OrFormation of pie bond due to breaking of sigma bond by side by side overlapping is called hyperconjugation | |

Boron triflouride behave as a lewis acid |
| Answer» The substance which can accept the electron pair donated by the Lewis base, they are termed as Lewis acid.\xa0is a compound which is made up of two atoms namely boron and fluorine.The atomic number of boron is 5 and its electronic setup is 2, 3. Its valency is 3 and Flourine (2,7) valency is 1.Consequently, by imparting 1 electron to every fluorine molecule, boron has 3 sigma bonds around it which means that each boron atom is surrounded by 6 electrons.To have the steady octet setup Boron needs 2 additional electrons.Since boron can accept a couple of electrons from Lewis base, it is considered as Lewis acid. | |

Is boric acid a protic acid? Explain |
| Answer» As you know, protic acid give proton in water , it is not a protic acid because it doesn\'t ionize in H2O to give a proton . it acts as Lewis acid by accepting electrons from a hydroxyl ion of water and in turn releases H+ ions.e.g., B(OH)3 + HOH ----> [B(OH)4]- + H+ | |

What are the characteristics of p block elements |
| Answer» \tThe p-block elements have relatively little in common except that their outer elections are in p orbitals.\tThis contrasts with the considerable similarities in properties of the elements of the s-block and also between those of the d-block.\tThe p-block is more notable for trends.\tThe general electronic configuration of these elements is ns2 np1-6.\tDepending upon the number of valence electrons, the elements of the p-block exhibit variable oxidation states. | |

Why lithium is soluble in pyridine |
| Answer» Since solvation energy of Lithium chloride is higher than that of Cesium chloride ,thus Lithium chloride is soluble in solvents such as Pyridine .Solvation energy is the amount of energy released when one mole of substance combine with the solvent or gets solvated in the solvent.Thus instead of high lattice energy in case of Lithium chloride it gets Soluble in pyridine. | |

What is Common-ion effect? |
| Answer» The common ion effect is an effect which results when two substances, which both ionize to give the same (common) ion, are involved in a chemical equilibrium.The solubility of a sparingly soluble salt is reduced in a solution that contains an ion in common with that salt. For instance, the solubility of silver chloride in water is reduced if a solution of sodium chloride is added to a suspension of silver chloride in water. | |
