What is redox reaction and higher level and examples |
| Answer» A redox reaction is a type of electrochemical reaction where oxidation and reduction occur simultaneously. Redox is the short form for “reduction and oxidation”.According to it oxidation is defined as ‘addition of oxygen or an electronegative element to a substance (or) removal of hydrogen (or) an electropositive element from a substance’.Reduction is the opposite of oxidation.\xa0Reduction can be defined as‘removal of oxygen (or) an electronegative element from a substance or addition of hydrogen (or) an electropositive element to a substance’.Example: When Methane reacts with Oxygen to give Carbon dioxide and water. During this reaction Carbon is oxidised due to removal of Hydrogen and simultaneously Oxygen is reduced due to addition of Hydrogen. | |

What are the merits and demerits of Mendeleev\'s periodic table |
| Answer» Merits are as follows:-\xa0i. There was a regular gradation in physical and chemical properties of elements.ii. The group number of an element indicates highest oxidation state that it can attain.iii. There were many vacant spaces in Mendeleev\'s periodic table for the elements to be discovered. He named them Eka-Boron, Eka-Aluminium and Eka-silicone He also predicted the properties of these undiscovered elements including atomic masses. These elements were discovered as Sc ,Ga and Ge with same features as he predicted.iv. Mendeleev’s arrangement helped to correct atomic masses of a number of elements.Demerits of Mendeleev’s periodic tablei. Mendeleev could not assign a correct position to hydrogen in the periodic table as hydrogen resembles alkali metals as well as halogens.ii. Isotopes had to be given the same position in the periodic table though isotopes of the same elements have different atomic masses.iii. It was observed that at certain places, an element of higher atomic mass Cobalt (Co=58.93) has been placed before an element of lower atomic mass Nickel (Ni = 58.71).iv. Some elements placed in the same sub - group varies in their properties. Manganese is placed with halogens which totally differ in the properties.\xa0 | |

What is saturated and what is unsaturated compounds |
| Answer» Saturated carbon compounds: These are the compounds in which various carbon atoms in a chain or a ring are linked together by single bonds only. Alkanes are the most common examples of saturated chain carbon compounds.Unsaturated carbon compounds: These are the compounds in which various carbon atoms in a chain or a ring are linked together by double or triple bonds. Alkenes (where carbon atoms are linked through double bonds) and alkynes (where carbon atoms are linked through triple bonds) are the most common examples of unsaturated chain carbon compounds. | |
