ClF is a inter-halogen compound. The fluorine is in -1 oxidation state and Cl is in +1 oxidation state. ClF can accept electrons because the chlorine has vacant d-orbitals. So, it can react with fluorine to form ClF​3. It can act as both lewis acid and lewis base. ClF can act as a Lewis base as in the presence of a strong lewis acid like AsF5 and accepting a fluoride ion from KF. ClF + KF→K+[ClF2]-

Saltpetre, also spelled Saltpeter, also called Nitre, or Niter, any of three naturally occurring nitrates, distinguished as ordinary saltpetre, or potassium nitrate, KNO3; Chile saltpetre, cubic nitre, or sodium nitrate, NaNO3; and lime saltpetre, wall saltpetre, or calcium nitrate, Ca(NO3)2. These three nitrates generally occur as efflorescences caused by the oxidation of nitrogenous matter in the presence of the alkalis and alkaline earths. .

Prince Jaat 8 years ago

Quantitatively, ozone can be estimated with the help of potassium iodide. When ozone is made to react with potassium iodide solution buffered with a borate buffer (pH 9.2), iodine is liberated. This liberated iodine can be titrated against a standard solution of sodium thiosulphate using starch as an indicator.

When carboxylic acids react with chlorine or bromine in the presence of red phosohorous, the alpha-hydrogen atoms are replaced by halogen atoms. It is called Hell-Volhard-Zelinsky(H.V.Z) reaction. Ex:- acetic acid reacts with chlorine in presence of red phosphorus to form chloro acetic acid, dichloro acetic acid or trichloro acetic acid depending on the quantity of chlorine reacting.

Because it is alkyl gr. And it exit from it

Sry -3 charge is less stable than +5

Harshit Tiwarri 8 years ago

Phosphorus par -5 charge stable nhi hai in pcl4-

Prince Jaat 8 years ago

The oxidation state of P in PCL4 + is +5 while in PCl4− is +3 as we know that the stability of the +5 oxidation state is high and decreases as we go down the group. On the contrary stability of +3 increases from top to bottom of the group. Hence, PCl4+ is more stable and likely to exist.

Vishal Malviya 8 years ago

Vishal Malviya 8 years ago

Pcl4- does not exist........ Pcl6- does..... Pcl6- is octahedral.. Pcl4+ is tetrahedral

Potassium permanganate (KMnO4) is a very strong oxidant able to react with many functional groups, such as secondary alcohols, 1,2-diols, aldehydes, alkenes, oximes, sulfides and thiols. Under controlled conditions, KMnO4 oxidizes primary alcohols to carboxylic acids very efficiently
