The rule says that in every addition reaction across the unsymmetrical double bond , the negative part of addendum molecule goes to that carbon atom having greatest no. of HYDROGEN.
Example - CH₃-CH=CH₂ +HBr → CH₃-CH₂-CH₂Br

Explain pyrolysis in easy way

Posted by ?????Geetanjali???? ? 7 years, 1 month ago

CBSE > Class 11 > Chemistry

1 answers

Yogita Ingle 7 years, 1 month ago

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.

Gaurav Seth 7 years, 1 month ago

Generally Van- dar waal's equation is written ,
( P + an²/V²)( V - nb) = nRT

where , P is the pressure
V is the volume , n is the no of mole of gases R is universal gas constant , T is te the temperature ( in K)
. also a and b are constant .

For one mole Van dar waal's equation is
( P + a/V²)( V - b) = RT

What do you mean by extensive properties? Give example

Posted by Golu Kumar 7 years, 1 month ago

CBSE > Class 11 > Chemistry

1 answers

Gaurav Seth 7 years, 1 month ago

Extensive Properties

Some properties of matter depend on the size of the sample, while some do not. An extensive property 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. The 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

Posted by Sunny Kumar 7 years, 1 month ago

1 answers

Harshdeep Kaur 7 years, 1 month ago

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.
