O nitrophenol is more reactive than p nitrophenol

Posted by Mukesh Bawa 8 years, 2 months ago

2 answers

Ujjawal Sharma 8 years, 2 months ago

It is more reactive because it have inter molecular h bonding and in p nitro phenol have intra molecular h bonding. So more energy is required in pnitrophenol. So p nitro phenol less reactive than o nitro phenol

The piezoelectric effect is understood as the linear electromechanical interaction between the mechanical and the electrical state in crystalline materials with no inversion symmetry.[5] The piezoelectric effect is a reversible process in that materials exhibiting the direct piezoelectric effect (the internal generation of electrical charge resulting from an applied mechanical force) also exhibit the reverse piezoelectric effect (the internal generation of a mechanical strain resulting from an applied electrical field). Ok or not

rie temperature (TC), or Curie point, is the temperature at which certain materials lose their permanent magnetic properties, to be replaced by induced magnetism. The Curie temperature is named after Pierre Curie, who showed that magnetism was lost at a critical temperature.
