Explain pyrolysis in easy way |
| Answer» Alkanes, when subjected to high temperature (670-970 K.) in the presence of a catalyst, are decomposed into smaller molecules. This process of breaking down the less volatile higher hydrocarbons into different types of more volatile lower hydrocarbons by the application of heat is called cracking or pyrolysis. The cracking of alkanes involves the cleavage of C-C and C-H bonds.\xa0 | |

What do you mean by extensive properties? Give example |
| Answer» Extensive PropertiesSome properties of matter depend on the size of the sample, while some do not. An\xa0extensive\xa0property is a property that depends on the amount of matter in a sample. The mass of an object is a measure of the amount of matter that an object contains. A small sample of a certain type of matter will have a small mass, while a larger sample will have a greater mass. Another extensive property is volume.\xa0The volume of an object is a measure of the space that is occupied by that object.Eg. The pitcher and glass both contain milk. The pitcher holds approximately two quarts and the glass will hold about 8 ounces of milk. The same milk is in each container. The only difference is the amount of milk contained in the glass and in the pitcher | |

I couldnt understand the concept of stability for carbanions and carbocation |
| Answer» It is dependent whether the group which is attached is electron releasing or withdrawing..... 1)In case of carbonation... If the group is electron releasing.... It is give electrons to it making it neutral and hence stable whereas electron withdrawing group will make it unstable.2)In case of Carbo anion.... If the group it electron withdrawing.... It will take extra electrons from it making it neutral and hence stable whereas electron releasing group will make it more unstable. | |
