what is the valence bond theory
Hey!
Valence bond theory or VB theory is a theory based on quantum mechanics that explains how chemical bonding works. In valence bond theory , the atomic orbitals of individual atoms are combined to form chemical bonds . The other major theory of chemical bonding is molecular orbital theory or MO theory .

methyl isocyanide reacts with mercuric oxide
Annapurna, this reaction is a very important reaction used for synthesis of methyl isocyanate ie a compound containing N=C=O group attached to a CH3- group. The reaction can be explained as follows:--
CH3NC + HgO ----->CH3N=C=O (majorproduct)
Hope this helps you.
which type of bond is RuO4 covalent or ionic?
hello aspirant..
Ruthenium tetroxide is the organic compound with this formula. It is a yellow volatile compoound that melts at the normal room temperature. they are black in colour due to the impurities. It is formed by the two co double bonds from the oxidative cleavage of cc double bonds. this compound is covalent in nature.
hope this helps
what are the difference between physisorption and chemisorption
In physisorption the molecules get adsorbed on the surface of adsorbent due to the weak wanderwall forces and the energy of adsorption is very low in case of chemisorption there is a chemical bond formed between the adsorbent and adsorbate in the energy of adsorption is very high.
What are the Important concepts or chapters one should study from class 11 so that he can be better at p blocks (class 12)?
Better to see you are grooming out towards JEE competitive exams and ready to tackle it.
For p block elements in chemistry you must keep hold on organic chemistry from your 11th standard . Keep recognising the periodic table day by day and be cool and confident.
How many isomeric acyclic alcohols and ethera are possible for C4H8O ?
There are in total 10 isomers possible from c4h8o which include aldehyde, ketone, alcohol and ether. Talking only about acyclic alcohol and ether, then there are five possibilities. They are Crotyl alcohol, 1,2 epoxybutane, 2,3 epoxybutane, Ethyl Vinyl ether, Tetrahydrofuran. Try out the structures.
Hope this helps.
Good luck!
the number of hydrogen atom(s) attached to phosphorus atom in hypo phosphorus acid is
Hello dear student !
The molecular formula of Hypophosphorous Acid is H3PO2 . Therefore, in the structure of this formula two Hydrogen atoms are attached to the phosphorous atom with single bond. Also one (-OH) is attached to phosphorous in the structure. with single bond and one oxygen atom is attached to phosphorous with double bond.
In nitretaion why the para position is mesor products?
Hello,
Actually this matters when you change the substance of the nitration. But usually when an ortho para substituent is present on the benzene ring for an electrophilic substitution reaction then the para product is always the major product because the electron density is higher on this position.
Hope it will be helpful for you.
Thank you.
what is lyophobic and lyophilic
Hello Anurag
First of all, the lyophobic and the lyophilic, both are colloids.
But the main difference is that the lyophilic colloids are solvent loving colloids. Means, there is a strong attraction between the lyophilic colloids and the liquid.
Whereas, the lyophobic colloids are solvent hating colloids. There is less or no attraction between the lyophobic colloids and the liquid.
I hope, you understood :)
