Posted by Sakshi Rawal 6 years, 6 months ago

CBSE > Class 12 > Chemistry

1 answers

Sia ? 6 years, 6 months ago

Azeotropes are binary mixtures having same composition in liquid and vapour phase and boil at a constant temperature. So the solutions (liquid mixtures) which boil at constant temperature and can distill unchanged in composition are called azeotropes.
Azeotropes are liquid mixtures which boil at constant temperature and distill out unchanged in their composition. For example, ethanol and H₂O.

See everything what we r learning is just for our knowledge..... 1st of all dont think why we should study this and that when it is not use ful. Organic chemistry is important when u want to go to bsc,Msc field.... or chemical engineer. Suppose u didnot get the engineering field which u want so u are having another option in chemistry field.

rules of organic chemistry are as follows:--- > Select the parent chain in the compound which should include the functional grp, max no. of multiple bonds nd also single bonds. > Identify the parent functional group the parent functional group should be give highest order of preference if there is more than one functional grp. >Identify the side chains. > functional grp nd side chains grp together acc. to alphabetical oder. >Identify the double and triple bonds. >Number the chain in both direction and check for the lowest-numbered for the suffix functional group, the lowest-number for the multiple bonds, double bonds and retain that numbering. >If there is more than one of the same type of double bond, a prefix is added showing how many there are. >Numbering the side chains and If there are two side-chains with the same alpha carbon, the number will be written twice.
