The formula of Zirconium hydride is not represented as `ZrH_(4)` but `ZrH_(1.92)`. Why?

The molecules of alkene family are represented by a general formula C_n H_(2n) . What is the molecular formula and name of the alkene when n = 4

Number of structural isomers represented by molecular formula C_4H_(10)O is

Dimensional formula ML^(-1)T^2 does not represent the physical quantity

The number of ether isomers represented by formula C_(4)H_(10)O is (only structral)

The following electrochemical cell is represented as : Pt(1)|Hg^(2+),Hg_(2)^(2+)(a=1)||Ce^(4+),Ce^(3+)(a=1)|Pt(2) a. If an ammeter is connected between two platinum electrodes, predict the direction of flow of current. b. Will the current decrease or increase with time? Given :E^(c-)._(2Hg^(2+)|Hg_(2)^(2+))=0.92V,E^(c-)._(Ce^(4+)//Ce^(3+))=1.61V

Which pair does not represent a cyclic compound of the formula C_(4)H_(6)

Statement-1 :The thermal stability of hydrides of carbon family is in order: CH_(4)gtSiH_(4)gtGeH_(4)gtSnH_(4)gtPbH_(4) Statement-2: E-H bond dissociation enthalpies of the hydrides of carbon family decrease down the group with increasing atomic size.

The number of alkanols and ethers represented by the molecular formulae C_(3) H_(8) O and C_(4) H_(10) O respectively are gives by the set :

Name any three types of isomerism that the compound with molecular formula C_4 H_7CI can give rise to. Also represent the structures of the compounds relevant to these isomers. ""^(**"**)
