putting it simply an 2p has 3 orbitals [ | | ] and where as 2p is entirely called as a subshell.

As far as i know its D1 = D2 theroitically but one guess i can do it that anti bonding orbital are far from nucleus than bonding orbtials. we know that nearer to nucleus lesser is the energy. I think this explains the fact you have told.

Look it not only the material that always matters it is also the medium that matters. CH3COOH is weak acid which breaks in the any polar solvent usually (like water) where it can conduct a bit of electricity due to presence of ions where as in a non polar medium or in it pure form it doesn't conduct.

He might have consider all possibilities and taken H2C=C=CH-CH3 in to account

In Ortho acetyl benoic acid the H atom of the _COOH group forms a Intramolecular Hydrogen bonding with oxygen atom of - C=O giving a stable 6 member ring hence this is not a free H available to be acidic unlike in para acetyl benzoic acid which can give only intermolecular H bonding.

Here the alkene stability is attained due to conjugation. (Two alternate double bonds can result in conjugation like in benzene). because alternate double bonds can lead to more resonanse structures.Only thing that has alternate double here is butadieneSome more Stability rules of Alkene::There are 3 factors that influence alkene stability:1. Degree of substitution: more highly alkylated alkenes are more stable, so tetra > tri > di > mono-substituted.2. Stereochemistry: trans > cis due to reduced steric interactions when R groups are on opposite sides of the double bond.3. Conjugated alkenes are more stable than isolated alkenes.

yes AgI will precipitate out. Solubility product is the product of concentration of Ions in the saturated solutions.
As we know after saturation limit salt doesnot dissolve in water similarly after reaching saturation limit the Ag+ and I- ions in solutions doesnt know what to do so they react and form AgI.

It will form trimethyl benzene

No guessing ... :PThe answer is enthene is formed. It is a special reaction where alkynes are stopped at alkene stage rather than converting to alkanes and other speciality of the reaction is they form cis alkenes

Platforming is Petroleum based chemical process where Pt is used as catalyst. I was first used in 1949 and recently in 1999 the inventor got a Noble prize for the samr

21% by volume means in 1000 ml we have 210 ml of OxygenNow by PV= nRT => 1 x 0.21 = n x 0.08214 x 273 => 0.0093

Yes, For physical adsorption it just dies down like -ve exponential where as for chemical adsorption is increases and then decrease like a bell curve

Look the definition of Hydration energy is it is the energy released due to the formation of hydrogen bonds between a cation and anion.From Columbs law of physics,The strength of attraction between two charges is directly proportional to the charge density and the radius.Assuming a common anion, All cations here has same charge hence charge density depends on the size. Larger the size small the density (charge per unit area.). The trend shows you the same.size : Cs > Rb > K> Na >LiHence Charge density: Li > Na > K > Rb > CsHence the trend.

This is not the case Pb3o4 exists actually as PbO and PbO2 Hence Oxidation state is +2 and +4
