In which of the following bonding is possible?
B.
Carbon, oxygen and nitrogen atoms do not have any d-orbital available. Therefore, in , there is no possibility of type of bonding.
In phosphorus atom has vacant d-orbital available which is used to form type of bonding with p-orbital of oxygen atom.
When the temperature of reactions will increase then the effect on pH value will
increase
decrease
first increases then decreases
remains same.
The pH of aqueous solution ofammonium formate is (pKa of HCOOH = 3.8 and pKb of NH3= 4.8)
7
6.0
