Ring substitution in aromatic ethers
Alkoxy group is ortho and para directing and it directs the incoming groups to ortho and para position. It becomes the aromatic ring leads to electrophilic substitution reaction.
III, IV and V points out high electron density at ortho and para position.
hypothesis for this lab "finding the missing mass"
what is chemistry
what are the topics which are covered under the assignment of de broglie hypothesis?
Water pressure is the same in all directions Punch holes around the base of a tall tin can with a nail. Wrap the holes as above with a strip of tape. Fill the can with water an
Q. Illustrate Oxidation States of f-block? The addition of the first three ionisation energies of the lanthanides is comparatively low, so the elements are highly electropositi
Q. Mention the role of insoluble fibres from wheat bran? The insoluble fibres from the wheat bran are resistant to fermentation by colonic bacteria and increase fecal bulk by r
The propyl group on carbon-4 has to be gauche to either the ethyl group or the isopropyl group. Due to the isopropyl group is larger, the propyl group is gauche to the ethyl group
Delocalisation of electrons in conjugated system is called resonance. For example there is delocalisation of electrons in benzene ,hence we write kekule structure for benzen.
Effect of substituent on acidic nature (a) An electron withdrawing substituent that is - I effect stabilizes the anion by dispersing the negative charge and hence increases the
Resonance effect - Effect of substituents on acidity Same as inductive effect, if the resonance producing group exerts minus effect that is, if it withdraws electrons, it raise
