Asserion: A small amount of ethanol is added to `CHCI_(3)` bottles.
Reason: It acts as negative catalyst for the oxidation of `CHCI_(3)` to `COCI_(2)`.

Name the catalyst used for the oxidation of SO_2 to SO_3 in contact process.

………..is used as catalyst for oxidation of SO_2 to SO_3 in contact process.

Writing the overall chemical equation from a mechanism: Carbon tetrachloride, C CI_(4) , is obtained by chlorinating methane or an incompletely chlorinated methane such as chloroform, CHCI_(3) . The mechanism for the gas phase chlorination of CHCI_(3) is CI_(2)hArr2overset(.)(C )I , Elementary reaction overset(.)(C )I+CHCI_(3)rarrHCI+overset(.)(C )CI_(3) , Elementary reaction overset(.)(C )I+overset(.)(C )CI_(3)rarrC CI_(4) , Elementary reaction Obtain the net, or overall, chemical equation from this mechanism Straregy : The overall chemical equation, which represents the net result of the elementary reaction in the mechanism, is obtined by adding the steps together and cancelling species that occur on borth sides.

Assertion: CHI_(3) gives a precipitate with AgNO_(3) solution on heating but CHCI_(3) not Reason: C-1 bond is quite weak as compound to C-CI bond .

Discuss the bromination of phenol in aqueous solution and CS_(2) or CHCI_(3) as solvent.

Vapour pressure of chlolfom (CHCI_(3)) and dichloromethane (CH_(2) CI_(2)) at 298 K are 200 mm Hg and 415 mm Hg respectively. Calculate the vapour pressure of the solution prespared by miximng 25 g of CHCI_(3) and 45 g of CH_(2) CI_(2) at 298 K. Also find the mole fraction of CHI_(3) in the vapour phase .
