I know that time is less but having having capability or showing capability to do anything matters. Make sure that you should do all the NCERT questions and at least the conversions given in NCERT. In a more better i would suggest you to go through perepations of compound in one day then next day go with the physical properties then go with chemical properties then revise it again and again.Try to do conversions more and more because they actually test how much you have learnt through the reactions. Have confidence in you and try to do?

The vapour pressure of pure benzene is 639.7mm of mercury and the vapour of solution of a solute in benzene at temprature is 631.9mm of mercury then find what is the molality of the solution

Vineet Kumar Gupta 7 years, 1 month ago

Let the molality of the solution =m Now the solution contains m moles of solute per 1000gm of benzene. Vapour pressure of pure benzene,P0=639.7mm Vapour pressure of solution ,P=631.9mm Moles of benzene (mol wt. 78)N=100078 Moles of solute,n=? Substituting these values in the Raoult's equations P0−PP0=nN 639.7−631.9639.7=n×781000 (Or) 7.8639.7=78n1000 ∴n=1000×7.878×639.7 ⇒0.156 Hence molality of solution =0.156mole/kg

How to convert into Benzoic acid into Bromobenzene

Posted by Ankit Kumar 7 years, 1 month ago

Priyanshu Sharma 5 years, 8 months ago

You could use a Hunsdiecker reaction. Treat the benzoic acid with silver(I)carbonate and elemental bromine in carbon tetrachloride. A radical decarboxylation yields the phenyl radical which reacts with dibromine to yield bromobenzene. This reaction was first observed by the Russian chemist and composer Alexander Borodin.
