Hot air has no "strange tendency" to rise..............


Hot air rises because it is light enough.........


(that is, lighter than the surrounding air) that gravity’s pull is less than the buoyant push.


The air below exerts greater pressure on the hot air than the air above. This pressure difference provides a buoyant force great enough to lift the lighter hot air.

1. First prepare yourselves mentally for IIT-JEE


 "The success is to be achieved", keeping this in mind the aspirants must accept themselves as deserving candidates for JEE success because during preparation confidence plays an important role.


2. Do continuous effort


IIT-JEE preparation requires continuous effort. Each subject must be given proper and regular time. Instead of preparing one subject for some days then other subjects, all the three subjects (Physics, Chemistry and (Mathematics) must be given time each day. It also helps in breaking monotony.


3. Have proper guidance


In today's competitive era, proper guidance is needed for success. The pattern of JEE has become concept based completely. So you need clear and doubtless concepts in each and every topic, to achieve a good rank in JEE.


4. Prepare good Notes


Prepare good notes during attending lectures or self study.


5. Do regular revision


Apportion proper time for each subject. The approach should be balanced.After systematically understanding the concepts practice relevant problems to consolidate the topic.


ALL THE BEST.........

Catalogs Discussion Forums -> Inorganic Chemistry -> rates assured please explain back bonding!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! -> Go to message
This Post 15 points    (Olaaa!! Perrrfect answer.   in 3 votes )   [?]

 


π backbonding, also called π backdonation,..............


in which electrons move from an atomic orbital on one atom to a π anti-bonding orbital on another atom or ligand.......................


It is especially common in the organometallic chemistry of transition metals with multi-atomic ligands.............


Electrons from the metal are used to bond to the ligand, in the process relieving the metal of excess negative charge.


The electrons are taken from a d-orbital of the metal, and usually placed into an anti-bonding molecular orbital of the ligand, which causes the bond order of that ligand to decrease.


 Although the bond-order within the ligand is decreased by this process, the metal - ligand bond-order is increased.


Compounds where π backbonding occurs include Ni(CO)4 and Zeise's salt.
