Because of -M (withdrawing) effect of ketone group, 3-Bromo Pentan-2-one has high partial positive charge on the carbon attatched to bromine, due to which neucleophile will have high tendency to attack, before bromine can leave, hence SN2 reaction takes place..........

The strongest acid among the following is (a) o-methoxy phenol (b) p-methoxy phenol (c) m-methoxy phenol (d) phenol
 
 
In case of m-methoxy phenol there is no destabilisation of phenolate as there is no negative charge on meta postion on resonating structure unlike para and ortho methoxy phenol hence it is...

THE QUESTION IS ABOUT INTERFACIAL AND SURFACE TENSION It is given that surface tension is the net downward pull or force if liquid (water) is taken but if two immiscible liquid is taken then...
 
 
At liquid-air interfaces, surface tension results from the greater attraction of water molecules to each other (due to cohesion) than to the molecules in the air (due to adhesion). The net...

Oxidation state of nitrogen in ncl3
 
 
nitrogen and chlorine have almost equal en ( 3.0 ).But nitrogen is smaller in size than chlorine. So chlorine is assigned +1 in NCl3, OS N = -3 and OS cl = +1

@ gman namg you were wrong Chlorine oxidation state is not fixed it may have -1(Nacl),+5(NaClO 3 ), +7(HClO 4 ) etc.
 
K Keerthirajan 8 days ago
 
the oxidation state of chlorine is fixed thus we can take out the value of nitrogen will be +3
